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, Option<Self::Item>)>

Consumes the given buffer (a part of a byte sequence), and decodes an item from it.

fn has_terminated(&self) -> bool

Returns true if the decoder cannot decode items anymore, otherwise false.

fn requiring_bytes(&self) -> ByteCount

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

impl BodyDecode for NoBodyDecoder

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

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