Module iobuf 

Buffer types for I/O operations.

Each buffer type is backed by one of three storage variants:

• Bytes/BytesMut: standard heap allocation (from From conversions)
• Aligned: untracked aligned allocation (from IoBufMut::with_alignment, pool bypass for small requests, or fallback)
• Pooled: tracked aligned allocation returned to a BufferPool on drop

Public types:

• IoBuf: Immutable byte buffer
• IoBufMut: Mutable byte buffer
• IoBufs: Container for one or more immutable buffers
• IoBufsMut: Container for one or more mutable buffers
• BufferPool: Pool of reusable, aligned buffers

Structs
