Trait buf_read_ext::BufReadExt [−] [src]

pub trait BufReadExt: BufRead {
    fn stream_until_token<W: Write>(&mut self, token: &[u8], out: &mut W) -> Result<usize> { ... }
}

Extends any type that implements BufRead with a stream_until_token() function.

Provided Methods

fn stream_until_token<W: Write>(&mut self, token: &[u8], out: &mut W) -> Result<usize>

Streams all bytes to out until the token delimiter is reached.

This function will continue to read (and stream) bytes from the underlying stream until the token or end-of-file byte is found. Once found, all bytes up to the token (if found) will have been streamed to out and this input stream will advance past the token (the token will be discarded).

This function will return Ok(n) where n is the number of bytes which were read, including the token if it was found. If the token was not found, it will still return Ok(n).

Errors

This function will ignore all instances of ErrorKind::Interrupted and will otherwise return any errors returned by fill_buf.
