Trait Encoder 

pub trait Encoder<Item, B: IoBufMut> {
    type Error: From<Error>;

    // Required method
    fn encode(&mut self, item: Item, buf: &mut B) -> Result<(), Self::Error>;
}

Trait for types that encode values into bytes.

Required Associated Types

type Error: From<Error>

The error type that can be returned during encoding operations.

Required Methods

fn encode(&mut self, item: Item, buf: &mut B) -> Result<(), Self::Error>

Encodes an item into bytes.

The buf is guaranteed to have 0 initialized bytes (buf_len() == 0). If the function is returned successfully, all initialized bytes will be treated as valid content to be transmitted.

Dyn Compatibility

This trait is dyn compatible.

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

Implementors

impl<B: IoBufMut> Encoder<Bytes, B> for BytesCodec

Available on crate feature bytes only.
