Trait PayloadCodec 

pub trait PayloadCodec: Sized {
    // Required methods
    fn encode(&self, out: &mut PayloadWriter);
    fn decode(input: &mut PayloadReader<'_>) -> Result<Self, PayloadDecodeError>;
}

A value with a payload form: the pure codec of a typed payload. Both functions see only the buffer, never a Host; decode must leave the reader just past the value and must not keep any of its input.

Required Methods

fn encode(&self, out: &mut PayloadWriter)

Writes the value. A failure is recorded on the writer.

fn decode(input: &mut PayloadReader<'_>) -> Result<Self, PayloadDecodeError>

Reads one value, leaving any following bytes to the caller.

Dyn Compatibility

This trait is not dyn compatible.

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