Additional notes

StructuralMap needs identity state only to keep variables consistent
when
descent rewrites a definition. Callback results are separate: callbacks
run
at every occurrence in their selected pre- or post-descent position.

Make default C++ descent the sole owner of FreeVar and DAG remapping,
with
definitions binding rewritten results and unchanged simple definitions
left
absent. Keep the remap ABI stable and use an owned raw-pointer-keyed
store for
efficient identity lookups.

Adopt whole raw TVMFFIAny results by value while leaving
destructor-visible
slot moves pointer-based. Initialize owning Any storage member-wise so
GCC
retains scalar state and avoids an overlapping narrow-store/wide-reload
stall.

Update existing C++ and Python expectations in place and document
StructuralMap as post(D(pre)) alongside StructuralWalk's stateless tree
traversal. Rust remains unchanged for a follow-up.

Additional notes

This PR refactor optimizes StructuralMap.

Move successful Expected payloads through structural-mutation hooks
without redundant reference-count traffic, while returning conversion
failures through Expected/Unexpected.
Require structural visit and mutation early returns to carry node
context, and document the public mutation-unwrapping macro.
Match callbacks before recursive descent so unmatched nodes skip
identity-remap lookup, error-frame setup, and callback-chain work.
Keep remap lookup and callback invocation inside each matched
continuation, preserving callback ordering and post-order target
revalidation.
Add registered-hook and error-context coverage for successful,
nullable, failing, and wrong-type mutation results.

This is the first release of tvm-ffi

Apache TVM FFI is an open ABI and FFI for ML systems. It is a minimal, framework-agnostic, yet flexible open convention with the following systems in mind:

Kernel libraries: ship one wheel to support multiple frameworks, Python versions, and different languages.
Kernel DSLs: reusable open ABI for JIT and AOT kernel exposure to PyTorch, JAX, and other ML runtimes.
ML frameworks and runtimes: unified mechanism to connect libraries and DSLs that adopt the ABI convention.
Coding agents: unified mechanism to package and ship generated code to production environments.
ML infrastructure: cross-language support for Python, C++, and Rust, and DSLs.

It has the following technical features:

DLPack-compatible Tensor data ABI to seamlessly support many frameworks such as PyTorch, JAX, CuPy and others that support DLPack convention.
Compact value and function calling convention for common data types in machine learning.
Stable, minimal, and flexible C ABI to support machine learning system use-cases.
Out-of-the-box multi-language support for Python, C++, Rust, and future path for other languages.
