prost-protovalidate-types

Generated Rust types for the buf.validate protobuf schema, built with prost and prost-reflect.

What this crate provides

• All message and enum types from buf/validate/validate.proto (e.g. FieldRules, MessageRules, OneofRules).
• A shared DESCRIPTOR_POOL containing the file descriptor set for runtime reflection.
• Extension traits for extracting constraint annotations from prost-reflect descriptors (FieldConstraintsExt, MessageConstraintsExt, OneofConstraintsExt, and more).

When to use this crate

Most users should depend on prost-protovalidate directly, which includes the evaluation engine and re-exports the types needed for validation.

Use prost-protovalidate-types when you only need the generated types or descriptor pool without the constraint evaluation engine.
