Trait Codec 

pub trait Codec<T> {
    type Error: Debug + Display + Send + Sync + 'static;

    // Required methods
    fn encode_header(
        &mut self,
        header: &Header<T>,

}

A Codec is responsible to encoding and decoding the data that is sent between cluster members.

So you can paint your bike shed however you like.

Required Associated Types

type Error: Debug + Display + Send + Sync + 'static

The codec error type. Will be wrapped by crate::Error.

Required Methods

fn encode_header( &mut self, header: &Header<T>, buf: impl BufMut, ) -> Result<(), Self::Error>

Encodes a foca::Header into the given buffer.

fn decode_header(&mut self, buf: impl Buf) -> Result<Header<T>, Self::Error>

Decode a Header from the given buffer.

Implementations MUST read a single item from the buffer and advance the cursor accordingly.

Implementations may assume the data in the buffer is contiguous.

fn encode_member( &mut self, member: &Member<T>, buf: impl BufMut, ) -> Result<(), Self::Error>

Encodes a Member into the given buffer.

Implementations MUST NOT leave the buffer dirty when there’s not enough space to encode the item.

fn decode_member(&mut self, buf: impl Buf) -> Result<Member<T>, Self::Error>

Decode a Member from the given buffer.

Implementations MUST read a single item from the buffer and advance the cursor accordingly.

Implementations may assume the data in the buffer is contiguous.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
