Trait linux::util::io::BufWrite

pub trait BufWrite: Write {
    fn read_to_eof<R>(&mut self, r: R) -> Result<usize>
    where
        R: Read;
    fn read<R>(&mut self, r: R, n: usize) -> Result<usize>
    where
        R: Read;
}

Objects that wrap a byte-stream for writing and contain a buffer.

Required methods

fn read_to_eof<R>(&mut self, r: R) -> Result<usize> where
    R: Read, 

Reads bytes from a Read object and writes them to the stream until end-of-file.

[argument, r] The object from which to read.

[return_value] Returns the number of bytes written.

= Remarks

If an error occurs, the error is returned immediately and the number of bytes copied is lost. No data is lost even if an error occurs.

fn read<R>(&mut self, r: R, n: usize) -> Result<usize> where
    R: Read, 

Reads up to a specified number of bytes for a Read object.

[argument, r] The object from which to read.

[argument, n] The maximum number of bytes to read.
