Struct Limited 

pub struct Limited<B> { /* private fields */ }

A length limited body.

This body will return an error if more than the configured number of bytes are returned on polling the wrapped body.

Hard-failing counterpart to BodyExt::collect_with: crossing the limit errors with LengthLimitError and discards the body. To instead keep the bytes read and forward the unread remainder (e.g. in a proxy), collect with a CollectOptions cap and recover via CollectError.

Implementations

impl<B> Limited<B>

pub fn new(inner: B, limit: usize) -> Limited<B>
