Trait BufWrite

Source

pub trait BufWrite: BufInterest {
    // Required methods
    fn write_buf<F, T, E>(&mut self, func: F) -> Result<T, E>
       where F: FnOnce(&mut BytesMut) -> Result<T, E>;

Expand description

trait generic over different types of write buffer strategy.

Required Methods§

Source

fn write_buf<F, T, E>(&mut self, func: F) -> Result<T, E>
where F: FnOnce(&mut BytesMut) -> Result<T, E>,

write into BytesMut with closure that output a Result type. the result type is used to hint buffer to stop wanting to flush IO on BufWrite::do_io or revert BytesMut to previous state before method was called.
