Struct bytecodec::tuple::Tuple4Encoder

pub struct Tuple4Encoder<E0, E1, E2, E3> { /* fields omitted */ }

Encoder for 4-elements tuples.

Methods

impl<E0, E1, E2, E3> Tuple4Encoder<E0, E1, E2, E3> where
    E0: Encode,
    E1: Encode,
    E2: Encode,
    E3: Encode, 

pub fn new(e0: E0, e1: E1, e2: E2, e3: E3) -> Self

Makes a new Tuple4Encoder instance.

pub fn inner_ref(&self) -> (&E0, &E1, &E2, &E3)

Returns references to the inner decoders.

pub fn inner_mut(&mut self) -> (&mut E0, &mut E1, &mut E2, &mut E3)

Returns mutable references to the inner decoders.

impl<E0: Default, E1: Default, E2: Default, E3: Default> Default for Tuple4Encoder<E0, E1, E2, E3>

fn default() -> Tuple4Encoder<E0, E1, E2, E3>

Returns the "default value" for a type.

type Item = (E0::Item, E1::Item, E2::Item, E3::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, t: 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.
