Struct bytecodec::combinator::WithPrefix

pub struct WithPrefix<E0, E1, F> { /* fields omitted */ }

Combinator for adding prefix items.

This is created by calling EncodeExt::with_prefix method.

Trait Implementations

impl<E0: Debug, E1: Debug, F: Debug> Debug for WithPrefix<E0, E1, F>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<E0, E1, F> Encode for WithPrefix<E0, E1, F> where
    E0: Encode,
    E1: Encode,
    F: Fn(&E0) -> E1::Item, 

type Item = E0::Item

The type of items to be encoded.

fn encode(&mut self, buf: &mut [u8], eos: Eos) -> Result<usize>

Encodes the items in the encoder and writes the encoded bytes to the given buffer.

fn start_encoding(&mut self, item: Self::Item) -> Result<()>

Tries to start encoding the given item.

fn requiring_bytes(&self) -> ByteCount

Returns the number of bytes required to encode all the items in the encoder.

fn is_idle(&self) -> bool

Returns true if there are no items to be encoded in the encoder, otherwise false.
