Trait Encoder
pub trait Encoder<Item> {
type Error: From<Error>;
// Required method
fn encode(
&mut self,
item: Item,
dst: &mut BytesMut,
) -> Result<(), Self::Error>;
}Expand description
Trait of helper objects to write out messages as bytes, for use with
FramedWrite.
Required Associated Types§
type Error: From<Error>
type Error: From<Error>
The type of encoding errors.
FramedWrite requires Encoders errors to implement From<io::Error>
in the interest of letting it return Errors directly.
Required Methods§
fn encode(&mut self, item: Item, dst: &mut BytesMut) -> Result<(), Self::Error>
fn encode(&mut self, item: Item, dst: &mut BytesMut) -> Result<(), Self::Error>
Encodes a frame into the buffer provided.
This method will encode item into the byte buffer provided by dst.
The dst provided is an internal buffer of the FramedWrite instance and
will be written out when possible.
