Module capnp_futures::serialize_packed

Asynchronous reading and writing of messages using the packed stream encoding.

Structs

PackedRead

An AsyncRead wrapper that unpacks packed data.

PackedWrite

An AsyncWrite wrapper that packs any data passed into it.

Functions

read_message

Asynchronously reads a message from reader.

try_read_message

Asynchronously reads a packed message from read. Returns None if read has zero bytes left (i.e. is at end-of-file). To read a stream containing an unknown number of messages, you could call this function repeatedly until it returns None.

write_message

Writes the provided message to writer. Does not call writer.flush(), so that multiple successive calls can amortize work when writer is buffered.
