[−][src]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.
