Module io 

I/O substrate: chunked buffer pool, fixed-size SPSC ring, and a transport abstraction layered on tokio.

The submodules provide the chunked buffer pool, the SPSC ring, and the reactor. The reactor module defines a Transport trait so that callers can plug in alternative wire transports (TCP and QUIC both ship) without changing the connection state machine.

Modules

cbuf

Fixed-size SPSC ring buffer.

mbuf

Pooled fixed-size byte buffers.

reactor

Async transport abstraction over the connection state machine.
