Struct RawBufVectored

pub struct RawBufVectored { /* private fields */ }

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

1. await the future with RawBuf Ready before drop the real buffer
2. make sure the pointer and length is valid before the future Ready

Implementations

impl RawBufVectored

pub const unsafe fn new(ptr: *const iovec, len: usize) -> Self

Create a new RawBuf with given pointer and length.

Safety

make sure the pointer and length is valid when RawBuf is used.

Trait Implementations

impl IoVecBuf for RawBufVectored

fn read_iovec_ptr(&self) -> *const iovec

Returns a raw pointer to iovec struct. struct iovec { void iov_base; / Starting address / size_t iov_len; / Number of bytes to transfer */ }; [iovec1][iovec2][iovec3]… ^ The pointer

fn read_iovec_len(&self) -> usize

Returns the count of iovec struct behind the pointer.

impl IoVecBufMut for RawBufVectored

fn write_iovec_ptr(&mut self) -> *mut iovec

Returns a raw mutable pointer to iovec struct. struct iovec { void iov_base; / Starting address / size_t iov_len; / Number of bytes to transfer */ }; [iovec1][iovec2][iovec3]… ^ The pointer

fn write_iovec_len(&mut self) -> usize

Returns the count of iovec struct behind the pointer.

unsafe fn set_init(&mut self, _pos: usize)

Updates the number of initialized bytes.
