Module buf_factory

Pooled buffers for zero-copy packet handling.

tokio-quiche maintains multiple buffer_pool::Pool instances for the lifetime of the program. Buffers from those pools are used for received network packets and HTTP/3 data, which is passed directly to users of the crate. Outbound HTTP/3 data (like a message body or a datagram) is provided by users in the same format.

BufFactory provides access to the crate’s pools to create outbound buffers, but users can also use their own custom buffer_pool::Pools. There are two types of built-in pools:

• The generic buffer pool with very large buffers, which is used for stream data such as HTTP bodies.
• The datagram pool, which retains buffers the size of a single UDP packet.
