Trait btlib::ReadDual

pub trait ReadDual: Read {
    // Required method
    fn read_into<W: Write>(&mut self, write: W, count: usize) -> Result<usize>;
}

The Read trait requires the caller to supply the buffer to be read into. This trait is its dual in the sense that the trait implementor is expected to supply its own buffer, which a Write instance is given. This can be used to avoid copying in cases where the trait implementor is already buffering data, so it can give a reference to this buffer to the caller (for example in SectoredBuf)

Required Methods

fn read_into<W: Write>(&mut self, write: W, count: usize) -> Result<usize>
