Struct ChainCodec

pub struct ChainCodec<T, U> { /* private fields */ }

Represents a codec that chains together other codecs such that encoding will call the encode methods of the underlying, chained codecs from left-to-right and decoding will call the decode methods in reverse order

Implementations

impl<T, U> ChainCodec<T, U>

pub fn new(left: T, right: U) -> Self

Chains two codecs together such that left will be invoked first during encoding and right will be invoked first during decoding

pub fn as_left(&self) -> &T

Returns reference to left codec

pub fn into_left(self) -> T

Consumes the chain and returns the left codec

pub fn as_right(&self) -> &U

Returns reference to right codec

pub fn into_right(self) -> U

Consumes the chain and returns the right codec

pub fn into_left_right(self) -> (T, U)

Consumes the chain and returns the left and right codecs

Trait Implementations

impl<T: Clone, U: Clone> Clone for ChainCodec<T, U>

fn clone(&self) -> ChainCodec<T, U>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T, U> Codec for ChainCodec<T, U>

where T: Codec + Clone, U: Codec + Clone,

fn encode<'a>(&mut self, frame: Frame<'a>) -> Result<Frame<'a>>

Encodes a frame’s item

fn decode<'a>(&mut self, frame: Frame<'a>) -> Result<Frame<'a>>

Decodes a frame’s item

impl<T: Debug, U: Debug> Debug for ChainCodec<T, U>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Default, U: Default> Default for ChainCodec<T, U>

fn default() -> ChainCodec<T, U>

Returns the “default value” for a type.

impl<T: PartialEq, U: PartialEq> PartialEq for ChainCodec<T, U>

fn eq(&self, other: &ChainCodec<T, U>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
