Trait Decoder 

pub trait Decoder<Item, B: IoBuf> {
    type Error: From<Error>;

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

Trait for decoding byte sequences back into structured items.

Required Associated Types

type Error: From<Error>

Errors happened during the decoding process

Required Methods

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

Decodes a byte sequence into an item.

The given buf is a sliced view into the underlying buffer, which gives one complete frame. Slice implements IoBuf.

You may escape the view by calling Slice::as_inner.

Dyn Compatibility

This trait is dyn compatible.

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

Implementors

impl<B: IoBuf> Decoder<Bytes, B> for BytesCodec

Available on crate feature bytes only.
