Trait i_o::TryRead [−] [src]

pub trait TryRead<T: Copy> {
    type Err;
    fn try_read(&mut self, buf: &mut [T]) -> Result<Result<usize, EndOfFile>, Self::Err> { ... }
    fn try_readv(&mut self, bufs: &mut [&mut [T]]) -> Result<Result<usize, EndOfFile>, Self::Err> { ... }

type Err

Provided Methods

fn try_read(&mut self, buf: &mut [T]) -> Result<Result<usize, EndOfFile>, Self::Err>

r.try_read(buf) = r.try_readv(&mut [buf])

fn try_readv(&mut self, bufs: &mut [&mut [T]]) -> Result<Result<usize, EndOfFile>, Self::Err>

Pull some data, at most bufs.fold(0, |n, buf| n+buf.len()), from this source into given buffers; return how many data were actually read, or a failure. If no data can be read when called, return 0 rather than wait.
