Module encode_sink 

Output abstraction for message encoding.

EncodeSink is the byte sink every encode path writes into. Its four required methods are the BufMut primitives the encoders bottom out in (the fixed-width signed/float writers are provided on top), plus put_shared for splicing an owned Bytes segment into the output without copying it.

Every BufMut implementor is an EncodeSink through a blanket impl, with put_shared copying — the contiguous behavior every existing caller already has. Rope implements the trait directly (it is deliberately not a BufMut) and captures large segments by reference count instead, so encoding a message whose dominant content is one large bytes field costs O(everything-but-the-payload) rather than O(payload).

Structs

Rope

A segmented encode sink: an ordered sequence of Bytes segments.

RopeBuf

A Buf over a finished rope’s segments, for consumers (hyper, h2, vectored writers) that take any Buf and iterate its chunks.

Constants

DEFAULT_MIN_SEGMENT

Default minimum segment size for Rope: payloads below this are copied into the small-write tail buffer rather than kept as their own segment.
