An extension for Read

Required Methods

fn try_read_exact( &mut self, buf: &mut [u8], pos_cb: impl FnMut(usize), ) -> Result<(), Error>

Tries to fill buf completely and calls the position callback pos_cb with the amount of bytes read on every successful read call

Note: This function behaves like read_exact, except that you will never loose state in case of an incomplete read - if the error is non-fatal (like TimedOut), you can always try again later if nothing happened

fn try_drain( &mut self, len: usize, pos_cb: impl FnMut(usize), ) -> Result<(), Error>

Tries to consume len bytes and calls the position callback pos_cb with the amount of bytes drained on every successful read call

Note: This function behaves similar to read_exact (without buffer), except that you will never loose state in case of an incomplete write - if the error is non-fatal (like TimedOut), you can always try again later if nothing happened

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
