Module io 

Stream framing and message I/O.

Traits

AsyncStream

A bidirectional byte stream capable of carrying RPC messages.

Functions

read_message

Reads one Cap’n Proto message (including its segment table) from the stream.

serialize_message

Serializes a Cap’n Proto message (including its segment table) to framed bytes. Synchronous so no non-Send capnp builder state is held across an await; write the result with write_raw.

write_raw

Writes already-framed bytes (as produced by serialize::write_message_to_words) to the stream.
