fn process_read_buf(
    &self,
    io: &IoRef,
    stack: &Stack,
    idx: usize,
    nbytes: usize
) -> Result<FilterReadStatus>

fn process_write_buf(&self, io: &IoRef, stack: &Stack, idx: usize) -> Result<()>

Process write buffer

fn shutdown(&self, io: &IoRef, stack: &Stack, idx: usize) -> Result<Poll<()>>

Gracefully shutdown filter

fn poll_read_ready(&self, cx: &mut Context<'_>) -> Poll<ReadStatus>

Check readiness for read operations

fn poll_write_ready(&self, cx: &mut Context<'_>) -> Poll<WriteStatus>

Check readiness for write operations
