Prost Validate
This is a Rust implementation of protoc-gen-validate.
It must be used with prost generated code.
All validation rules are documented in the proto file
or in the protoc-gen-validate
documentation.
It provides two implementations:
The test suite adapted from
the protoc-gen-validate harness tests
is shared between the two implementations.
Here are the benchmarks for the tests suite of the two implementations:
prost-reflect-validate:
harness reflect time: [14.849 ms 15.128 ms 15.459 ms]
prost-validate:
harness derive time: [2.5635 ms 2.5780 ms 2.5967 ms]
