Struct AccessSink 

pub struct AccessSink { /* private fields */ }

Holds records back until the response they describe actually exists.

A handler knows what it produced; it does not know what was sent. Response compression runs after the handler returns, so a record emitted there can only ever report the uncompressed body — which is the wrong number for anything that costs money. A transport that can measure the final body installs a sink here, hooks defer into it, and the transport drains it once the body is final. A transport that installs no sink gets inline emission, so the immediate-vs-deferred choice is made in exactly one place.

Implementations

impl AccessSink

pub fn new() -> Self

pub fn defer(&self, record: DeferredRecord)

Queue a record for emission once the response size is known.

pub fn emit(&self, response_bytes: Option<u64>)

Emit every deferred record, stamping response_bytes when known.

pub fn is_empty(&self) -> bool

True when no record is waiting — the transport can skip attaching it.
