Module write 

Write-side helpers: the cancellation-safe write arm and the teardown delivery/flush.

Enums

Wrote 🔒

One outcome of write_or_flush.

Constants

GRACEFUL_FLUSH_TIMEOUT 🔒

Upper bound on the teardown flush of a graceful DISCONNECT, so shutdown cannot hang on a peer that stopped reading.

Functions

deliver_and_flush 🔒

Delivers buffered messages to the application (they are acknowledged and owed to it) and, on a graceful close, flushes any remaining outbound bytes.

write_or_flush 🔒

Writes one chunk of pending to write, or flushes when pending is empty.
