Trait Codec 

pub trait Codec: Sized {
    type Error: Debug;
}

A serialization family.

Implemented once per family (not per message type) so that the family’s error type is declared in one place and CodecFor<T> can stay a blanket impl over whatever bound the underlying library needs. Codecs are zero-sized markers; they are named as type parameters and never instantiated.

Required Associated Types

type Error: Debug

Error returned by both CodecFor::encode and CodecFor::decode.

Typically the backing library’s own error, widened where the codec adds failure modes of its own (a too-small destination buffer, say).

Dyn Compatibility

This trait is not dyn compatible.

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