Raise the minimum Rust version to 1.85 by @LucaCappelletti94 in #87
What's Changed

Raise the minimum Rust version to 1.85 by @LucaCappelletti94 in #87

Ship the imported google.protobuf schemas by @LucaCappelletti94 in #86

Add utoipa feature to prost-wkt-types by @AlJohri in #88

Corrected the schemars and utoipa schemas: Duration accepts negative values and no longer claims format: duration, Timestamp no longer claims format: date-time, and Any only requires @type. utoipa components are registered as google.protobuf.*.

The schemars and utoipa features are now built and tested in CI and enabled on docs.rs

Notes

prost-wkt-types now vendors the google.protobuf well-known type schemas (protobuf v35.1), so the generated code no longer depends on the installed protoc or on protox. These files are BSD-3-Clause, so the crate's license expression is now Apache-2.0 AND BSD-3-Clause.

The minimum supported Rust version is now 1.85.

0.5.09 Oct 2023Deprecated

Fix deprecated use of DateTime::from_utc() by @Leulz in #55

Update to Prost 0.12.x series. This implements the new Name trait which can provide the type url in future. It is only partially implemented for now. Once fully stabilized, we need to see if it can potentially replace the type url method in MessageSerde (#53).
