Trait Filter

Required Methods

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

Accesses internal filter information.

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

Processes incoming read-buffer data.

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

Processes outgoing write-buffer data.

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

Performs a graceful shutdown of the filter.

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

Checks whether read operations may proceed.

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

Checks whether write operations may proceed.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
