PeekRead

Enum PeekRead

pub enum PeekRead {
    Read(usize),
    Error(Error),
    Cutoff(PeekCutoff),
}

Available on crate feature std only.

Expand description

Outcome of a single PeekWaiter::read.

Variants§

Read(usize)

Bytes read into the buffer, 0 meaning EOF.

Error(Error)

Reading failed.

Cutoff(PeekCutoff)

A PeekCutoff stopped the peek, see PeekWaiter::check.
