0.18.019 Sept 2026Breaking
With the summaries feature, toml is updated to 1.1.4 ( #600 ). Error::TomlSerializeError now wraps toml 1.x's ser::Error , a breaking change for code…
Added

PlatformSpec::Platforms, a new variant holding a list of platforms
(#438, #630), and PlatformSpec::platforms, a constructor that accepts
any iterator of Platform or Arc<Platform>. A query against Platforms is
enabled if it is enabled on at least one of the platforms. Platforms([]) is
the union of no platforms: nothing is enabled on it, not even unconditional
dependencies.

Per-platform results are combined with the same Kleene K3
OR
that guppy already uses to combine a dependency's target specs for a single
platform: Enabled wins, then Unknown, then Disabled.

Changed

Queries and link visitors:

PackageQuery and FeatureQuery are now represented as a set of initial
nodes plus a direction, sharing their internal bitset representation with
PackageSet and FeatureSet (#609, #610).

PackageQuery::initials now returns a &PackageSet, and
FeatureQuery::initials a &FeatureSet, rather than iterators over
metadatas. To obtain the old iterators, use
initials().packages(direction) and initials().features(direction).

PackageQuery::starts_from and FeatureQuery::starts_from are removed.
Use initials().contains(id) instead, which returns the same
Result<bool, Error>.

The Debug output of both query types now goes through the set types'
Debug impls. PackageQuery's Debug no longer dumps the entire
package graph, and FeatureQuery's now prints its initial packages with
their features.

The package and feature "resolver" traits are renamed and now receive an
opaque context (#497, #601, #602, #604):

PackageResolver is now PackageLinkVisitor, and FeatureResolver is
now FeatureLinkVisitor. The "resolver" name was easily confused with
the Cargo feature resolver, and the trait visits links rather than
packages or features.

accept is now visit_link on both traits.

visit_link (and the closures passed to PackageQuery::resolve_with_fn
and FeatureQuery::resolve_with_fn) takes a &PackageLinkContext or
&FeatureLinkContext instead of a &PackageQuery or &FeatureQuery.
The query is available via query(); the context also provides
direction() and starts_from_initial(&link).

CargoSet::with_package_resolver is now
CargoSet::with_cargo_link_visitor and takes a new CargoLinkVisitor
trait (in guppy::graph::cargo). Its CargoLinkContext exposes which
pass the link is being evaluated for (build_platform()), the platform
specs in effect (platform_spec() and build_dep_platform_spec()), and
whether dev and build dependencies are under consideration for the link
(considers_dev_deps and considers_build_deps respectively).

With the proptest1 feature, Prop010Resolver is now
Prop010LinkVisitor and PackageGraph::proptest1_resolver_strategy is
now proptest1_link_visitor_strategy.

Cargo sets and their inputs:

CargoOptions::new now defaults to version 3 of the Cargo feature
resolver
rather than version 1 (#624). To restore the old behavior, call
set_resolver(CargoResolverVersion::V1).

A new CargoSetInputs struct in guppy::graph::cargo combines
CargoOptions and the features-only set, and CargoSet now keeps a copy
of the inputs it was built with, available via CargoSet::inputs
(#627). CargoSet::features_only is removed; use
inputs().features_only instead.

With the summaries feature, CargoOptionsSummary is renamed to
CargoSetInputsSummary, and CargoSet::to_summary uses the inputs the
set was built with (#625). Each features-only entry now records
whether the package's base feature is enabled, writing base = false when
it isn't (#626). The field defaults to true, so existing summaries
continue to work.

Platform specs:

PlatformSpec::Platform is removed in favor of PlatformSpec::Platforms
(see above). With the summaries feature, PlatformSpecSummary::Platform
is likewise replaced by
PlatformSpecSummary::Platforms(Vec<PlatformSummary>) (#630).

A single platform is still serialized as-is, so existing serialized data
continues to work. Zero or several platforms are serialized as an array
(target-platform = [] or [[target-platform]]), which older versions of
guppy cannot read.

With the summaries feature, PlatformSpecSummary::to_platform_spec now
returns PlatformSpecSummaryError, which names the platform that could not
be converted, instead of a bare TargetSpecError (#628). The error also
records the position of the failing platform within a list, available via
its index and count methods. Both its Display output and
Error::InvalidPlatformSpecSummary's name the triple and, for a list, the
position.

Malformed platform specs now produce errors that name the offending
element or key, rather than serde's "data did not match any variant"
message (#629). The following are rejected: "always" and "any" inside
a list; spec alongside any platform key such as triple or
target-features; unknown keys in a platform table; empty triples; and
spec values other than "always" or "any". (Previously,
spec = "<triple>" was silently treated as that platform.)

PackageMetadata::minimum_rust_version is renamed to
PackageMetadata::rust_version, replacing the deprecated method of that
name (#616). As a result, rust_version now returns Option<&Version>
rather than Option<&VersionReq>.

Code that calls .matches(version) on the old return value will fail to
compile; use version >= *rust_version instead.

For code that displays or serializes these versions, the output will
change from a requirement such as >=1.65.0 to a plain version such as
1.65.0.

With the summaries feature, toml is updated to 1.1.4 (#600).
Error::TomlSerializeError now wraps toml 1.x's ser::Error, a breaking
change for code that names that type. Summaries are parsed strictly
according to the TOML 1.1 specification; documents that the lenient toml
0.5 parser accepted but that are not valid TOML are now rejected.

MSRV updated to Rust 1.91, as required by dependencies.

Removed

The following deprecated APIs are removed (#616):

PackageMetadata::rust_version's old form, deprecated since 0.17.1, which
returned an Option<&VersionReq> with a single >=X.Y.Z comparator
synthesized from the rust-version field. See the rename above for the
replacement.

BuildTarget::doc_tests, deprecated since 0.17.16. Use
BuildTarget::doctest_by_default instead.

PlatformSpec::current, deprecated since 0.17.13. Use
PlatformSpec::build_target instead.

The hidden re-export of the debug_ignore crate at the root of guppy.
Depend on debug-ignore directly if
you need it.

Fixed

FeatureSet::union, intersection, difference and symmetric_difference
now panic, as documented, if the two sets were built from different package
graphs (#608). Previously the check compared self's graph against itself
and could never fire, so mismatched sets silently produced an invalid result.
(The corresponding PackageSet operations already checked this correctly.)

With the summaries feature, rebuilding Cargo set inputs from a summary no
longer silently drops the features-only set (#625).

Additional notes2 sources agree

Added

Hakari::structural_excludes and Hakari::is_structural_excluded report
the structural excludes: the packages that are never added to the
workspace-hack, described under Fixed below.

Changed

Hakari::toml_name_map now returns an iddqd::IdOrdMap of TomlNameEntry
values, keyed and ordered by the name each dependency is written out under.
Updated toml to 1.1.4 and toml_edit to 0.25.13.
- HakariConfig::from_str, HakariBuilderSummary::to_string and
  HakariBuilderSummary::write_to_string now return error types from toml
  1.x, and TomlOutError::Toml wraps toml 1.x's ser::Error, a breaking
  change for code that names those types.
- Configuration files are parsed strictly according to the TOML 1.1
  specification; documents that the lenient toml 0.5 parser accepted but
  that are not valid TOML are now rejected.
Updated the re-exported diffy to 0.5.2. hakari does not enable any of
diffy's optional features. To use PatchFormatter::with_color, add a
direct dependency on diffy 0.5 with the color feature enabled.
MSRV updated to Rust 1.91, as required by dependencies.

Fixed

Hakari no longer adds third-party packages that depend on the workspace-hack
package, or on a workspace member that hakari manages, directly or
transitively through normal or build dependencies. (Dev-only dependencies are
ignored, since Cargo permits cycles through them.) This typically happens when a
workspace member is also published and a [patch] section redirects the
published version's workspace-hack dependency back into the workspace. In
that case hakari would end up introducing a cycle (#499).
The fixpoint step of the computation no longer adds workspace packages to
Hakari::computed_map or Hakari::output_map. Previously, a third-party
package that depended on a workspace member could cause that member to be
added to the workspace-hack, which would form a cycle.
Generated names for path and workspace dependencies no longer depend on
camino's Hash implementation, which changed in camino 1.2.3. The
output now matches hakari built against camino 1.2.2 and earlier. Builds
of hakari 0.17.9 against camino 1.2.3 or later produced different names;
those revert to the original names with this release.
Updated guppy to 0.19.0, which fixes a number of bugs around Cargo simulation.
In our testing across several real-world workspaces, we did not find any
where the workspace-hack contents changed. If they changed for you, please
update your workspace-hack Cargo.toml.

New config option workspace-hack-line-style, with three possible values:

"full": my-workspace-hack = { version = "0.1", path = ... }. This is the default and a good way to get started.
"version-only": my-workspace-hack = { version = "0.1" }. Specifying versions this way is useful if you've published a stub crate to crates.io (see the publishing section). You can use this in combination with a patch directive in the root Cargo.toml:
```
[patch.crates-io.my-workspace-hack]
path = "workspace-hack"
```

"workspace-dotted": my-workspace-hack.workspace = true. To use this, define a workspace dependency in the root Cargo.toml:

[workspace.dependencies]
my-workspace-hack = { version = "0.1", path = "workspace-hack" }

# or, along with a patch directive:
my-workspace-hack = { version = "0.1" }

Changed

Updated toml to 1.1.4. The on-disk format written by
Summary::write_to_string is unchanged: summaries are now written by the new
toml_compat module, which reproduces the output of toml 0.5's pretty
serializer, including its ordering of nested metadata tables. This is a
breaking change for code that names the following types:
- Summary::metadata is now toml 1.x's Table.
- Summary::parse, Summary::with_metadata, Summary::to_string and
  Summary::write_to_string return toml 1.x's error types.
- Summary::with_metadata no longer rejects metadata whose fields are
  declared out of TOML emission order; the fields are reordered when the
  summary is constructed instead.
- SummaryDiff is still serialized with toml's own serializer, whose
  blank-line placement differs slightly from 0.5.
Summaries are parsed strictly according to the TOML 1.1 specification;
documents that the lenient toml 0.5 parser accepted but that are not valid
TOML are now rejected.
MSRV updated to Rust 1.91, as required by dependencies.

hakari now outputs packages corresponding to the intersection of all platforms, then outputs any other platform-specific packages left. This simplifies the output greatly and is also more correct.
A new option final_excludes to remove packages from the result at the end of computation.
- This is in constract to traversal_excludes (renamed from omitted_packages) which removes packages both during and after computation.
A new cli-support feature contains several new structs used by cargo-hakari.
In HakariBuilderSummary, version = "v2" etc has been renamed to resolver = "2" to align with cargo.
- The old options will continue to work.
In HakariBuilderSummary, traversal-excludes and final-excludes are now easier to describe while deserializing: they now take a workspace-members list of names, and a third-party list of specifiers such as { name = "serde", version = "1" }.
- The resolver will now also fail if any specifiers are unmatched.

Changed

omitted_packages renamed to traversal_excludes.
Because of the changes to how excludes are represented, old-style HakariBuilderSummary instances may no longer parse correctly.
