Struct httpcodec::NoBodyDecoder

pub struct NoBodyDecoder;

A body decoder that consumes no bytes.

This does consume no bytes and immediately returns () as the decoded item.

It is mainly intended to be used for decoding HEAD responses. It can also be used to prefetch the HTTP header before decoding the body of a HTTP message.

Trait Implementations

impl Debug for NoBodyDecoder

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

Formats the value using the given formatter.

impl Default for NoBodyDecoder

fn default() -> NoBodyDecoder

Returns the "default value" for a type.

impl Decode for NoBodyDecoder

type Item = ()

The type of items to be decoded.

fn decode(&mut self, _buf: &[u8], _eos: Eos) -> Result<usize>

Consumes the given buffer (a part of a byte sequence), and proceeds the decoding process.

fn finish_decoding(&mut self) -> Result<Self::Item>

Finishes the current decoding process and returns the decoded item.

fn requiring_bytes(&self) -> ByteCount

Returns the lower bound of the number of bytes needed to decode the next item.

fn is_idle(&self) -> bool

Returns true if there are no items to be decoded by the decoder at the next invocation of decode method, otherwise false.

impl BodyDecode for NoBodyDecoder

fn initialize(&mut self, header: &Header) -> Result<()>

This method is called before starting to decode a HTTP body.
