🧩 Implementations for common protobuf types

This crate provides implementations for several well known protobuf types, such as those from google.protobuf, google.rpc and google.type, plus some implementations for buf.validate which are used by protocheck.

You can use feature flags to selectively include the implementations that you're interested in.

🗒️ List of implementations

Each struct/enum includes the default impls from prost such as Clone, Debug and so on.

The following features can also enable a variety of automatically derived implementations:

[cel] (TryInto cel::Value)
[serde] (Serialize, Deserialize)
[diesel] (FromSql, ToSql, FromSqlRow, QueryId, AsExpression)
- The diesel backend must be specified in the feature (i.e. diesel-postgres, diesel-sqlite, diesel-mysql)

In addition, the types from the google packages come with the implementations listed below, plus a variety of utility methods and helpers that can be found in the documentation.

All of the structs that have fallible methods also come with their own custom error enum.
