Struct Plain 

pub struct Plain;

Passthrough layer: no codec, no staging buffer, no codec state.

All trait methods are no-ops; pool’s IS_PASSTHROUGH branch never dispatches them.

Trait Implementations

impl CodecLayer for Plain

const IS_PASSTHROUGH: bool = true

True if this layer bypasses the codec staging path. Pool branches on this const to pick the direct fill_msghdr path (passthrough) vs the write_buf → process_outbound → take_inflight path (codec). The branch is monomorphized → DCE.
