Trait Encoder 

pub trait Encoder {
    type Item;
    type Error: Debug;

    // Provided methods
    fn encode(&self, _: Self::Item, _: &mut BytesMut) -> Result<(), Self::Error> { ... }
    fn encodev(
        &self,
        item: Self::Item,
        dst: &mut BytePages,
    ) -> Result<(), Self::Error> { ... }
}

Trait of helper objects to write out messages as bytes.

Required Associated Types

type Item

The type of items consumed by the Encoder

type Error: Debug

The type of encoding errors.

Provided Methods

fn encode(&self, _: Self::Item, _: &mut BytesMut) -> Result<(), Self::Error>

👎Deprecated since 1.2.0:

Implement .encodev() method.

Encodes a frame into the buffer provided.

fn encodev( &self, item: Self::Item, dst: &mut BytePages, ) -> Result<(), Self::Error>

Encodes a frame into the buffer provided.

Dyn Compatibility

This trait is dyn compatible.

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

Implementations on Foreign Types

impl<T> Encoder for Rc<T>

where T: Encoder,

type Item = <T as Encoder>::Item

type Error = <T as Encoder>::Error

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

👎Deprecated since 1.2.0:

Implement .encodev() method.

fn encodev( &self, item: Self::Item, dst: &mut BytePages, ) -> Result<(), Self::Error>

Implementors
