Struct bytecodec::combinator::PreEncode

pub struct PreEncode<E> { /* fields omitted */ }

Combinator for pre-encoding items when start_encoding method is called.

This is created by calling EncodeExt::pre_encode method.

Trait Implementations

impl<E: Debug> Debug for PreEncode<E>

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

Formats the value using the given formatter.

impl<E: Default> Default for PreEncode<E>

fn default() -> PreEncode<E>

Returns the "default value" for a type.

impl<E: Encode> Encode for PreEncode<E>

type Item = E::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.

fn cancel(&mut self) -> Result<()>

Cancels the current encoding and makes the encoder's state idle.

impl<E: Encode> ExactBytesEncode for PreEncode<E>

fn exact_requiring_bytes(&self) -> u64

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