Module buf

Utilities for working with buffers.

io_uring APIs require passing ownership of buffers to the runtime. The crate defines IoBuf and IoBufMut traits which are implemented by buffer types that respect the io_uring contract.

Structs

IoVecWrapper

A wrapper to make IoVecBuf impl IoBuf.

IoVecWrapperMut

A wrapper to make IoVecBufMut impl IoBufMut.

MsgMeta

RawBuf

RawBuf is not a real buf. It only hold the pointer of the buffer. Users must make sure the buffer behind the pointer is always valid. Which means, user must:

RawBufVectored

RawBufVectored behaves like RawBuf. And user must obey the following restrictions:

Slice

An owned view into a contiguous sequence of bytes. Slice implements IoBuf.

SliceMut

An owned view into a contiguous sequence of bytes. SliceMut implements IoBuf and IoBufMut.

VecBuf

A intermediate struct that impl IoVecBuf and IoVecBufMut.

Traits

IoBuf

An io_uring compatible buffer.

IoBufMut

A mutable io_uring compatible buffer.

IoVecBuf

An io_uring compatible iovec buffer.

IoVecBufMut

A mutable io_uring compatible iovec buffer.

MsgBuf

An io_uring compatible msg buffer.

MsgBufMut

An io_uring compatible msg buffer.
