The Read trait provides a means of reading from byte streams.

Required methods

`fn read(&mut self, buf: &mut [u8]) -> ParseResult<usize>`[src]

Read a number of bytes into the provided buffer. The returned value is Ok(n) if a read was successful, and n bytes were read (n could be 0).

Provided methods

`fn read_exact(&mut self, buf: &mut [u8]) -> ParseResult<()>`[src]

Read exactly the required number of bytes. If not enough bytes could be read the function returns Err(_), and the contents of the given buffer is unspecified.
