Required Methods

fn query(&self, id: TypeId) -> Option<Box<dyn Any>>

fn process_read_buf( &self, ctx: FilterCtx<'_>, nbytes: usize, ) -> Result<FilterReadStatus>

fn process_write_buf(&self, ctx: FilterCtx<'_>) -> Result<()>

Process write buffer

fn shutdown(&self, ctx: FilterCtx<'_>) -> Result<Poll<()>>
