[][src]Struct sgx_tstd::io::IoSlice

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

A buffer type used with Write::write_vectored.

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


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

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

Creates a new IoSlice wrapping a byte slice.


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

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

Advance the internal cursor of the slice.


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 IoSlices, both of length 8, and we advance the cursor by 10 bytes the first IoSlice will be untouched however the second will be modified to remove the first 2 bytes (10 - 8).
