Module early_data 

Available on crate features http and std only.

Early-data transmission facts and rejection errors. HTTP facts used by early-data recovery policies.

These extensions do not depend on the Retry layer. A custom client service can grant an attempt-local EarlyDataPermit, retain a replayable request, and inspect EarlyDataAttempt or EarlyDataRejected after sending. Recover at most once, with ForbidEarlyData retained for subsequent attempts. Only original requests with actual early-send evidence may recover HTTP 425; gateways pass that response back to its original owner.

Custom servers and gateways can inspect EarlyDataReceived and await its confirmation without any retry middleware. Inherited Early-Data exposure remains independent of the current connection’s handshake.
