Trait RustType 

pub trait RustType<Proto>: Sized {
    // Required methods
    fn into_proto(&self) -> Proto;
    fn from_proto(proto: Proto) -> Result<Self, TryFromProtoError>;

    // Provided method
    fn into_proto_owned(self) -> Proto { ... }
}

A trait for representing a Rust type Self as a value of type Proto for the purpose of serializing this value as (part of) a Protobuf message.

To encode a value, use RustType::into_proto() (which should always be an infallible conversion).

To decode a value, use the fallible RustType::from_proto(). Since the representation type can be “bigger” than the original, decoding may fail, indicated by returning a TryFromProtoError wrapped in a Result::Err.

Convenience syntax for the above methods is available from the matching ProtoType.

Required Methods

fn into_proto(&self) -> Proto

Convert a Self into a Proto value.

fn from_proto(proto: Proto) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

Since Proto can be “bigger” than the original, this may fail, indicated by returning a TryFromProtoError wrapped in a Result::Err.

Provided Methods

fn into_proto_owned(self) -> Proto

A zero clone version of Self::into_proto that types can optionally implement, otherwise, the default implementation delegates to Self::into_proto.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
