[][src]Struct sgx_tstd::io::IoSliceMut

#[repr(transparent)]pub struct IoSliceMut<'a>(_);

A buffer type used with Read::read_vectored.

It is semantically a wrapper around an &mut [u8], but is guaranteed to be ABI compatible with the iovec type on Unix platforms and WSABUF on Windows.

Methods

impl<'a> IoSliceMut<'a>[src]

pub fn new(buf: &'a mut [u8]) -> IoSliceMut<'a>[src]

Creates a new IoSliceMut wrapping a byte slice.

Panics

Panics on Windows if the slice is larger than 4GB.

pub fn advance<'b>(
    bufs: &'b mut [IoSliceMut<'a>],
    n: usize
) -> &'b mut [IoSliceMut<'a>]
[src]

Advance the internal cursor of the slice.

Notes

Elements in the slice may be modified if the cursor is not advanced to the end of the slice. For example if we have a slice of buffers with 2 IoSliceMuts, both of length 8, and we advance the cursor by 10 bytes the first IoSliceMut will be untouched however the second will be modified to remove the first 2 bytes (10 - 8).
