Trait BufRead

pub trait BufRead: Read {
    // Required methods
    fn fill_buf(&mut self) -> Result<&[u8]>;
    fn consume(&mut self, amount: usize);
}

A trait describing an input stream that uses an internal buffer when reading.

Required Methods

fn fill_buf(&mut self) -> Result<&[u8]>

Returns data read from this reader, filling the internal buffer if needed.

fn consume(&mut self, amount: usize)

Marks the buffered data up to amount as consumed.

Panics

May panic if amount is greater than amount of data read by fill_buf.

Object Safety

This trait is not object safe.
