Struct rexsgdata::SgList

pub struct SgList { /* fields omitted */ }

Wrapper for a C-style scatter gather list

Methods

impl SgList

pub fn new(iovec: *const iovec, count: usize) -> Self

Constructs new SgList object from raw arguments

pub fn into_inner(self) -> (*const iovec, usize)

Deconstructs the SgList object into original building blocks.

pub unsafe fn index_unchecked(&self, idx: isize) -> &iovec

Returns a reference to a idx' element of this Scatter Gather List

pub unsafe fn iter(     &self ) -> impl Iterator<Item = &iovec>

Iterates over &iovec stored in this SgList

pub unsafe fn iter_slices(     &self ) -> impl Iterator<Item = &[u8]>

Iterates over byte slices &u8

pub unsafe fn iter_slices_mut(     &self ) -> impl Iterator<Item = &mut [u8]>

Iterates over byte slices &u8

pub unsafe fn iter_range(     &self ) -> impl Iterator<Item = (&iovec, Range<usize>)>

Iterates over tuples of &iovec and associated Range describing this iovec position in the whole SgList

pub unsafe fn iter_slices_range(     &self ) -> impl Iterator<Item = (&[u8], Range<usize>)>

Iterates over tuples of &[u8] slices and associated Range describing this slice position in the whole SgList

pub unsafe fn iter_slices_range_mut(     &self ) -> impl Iterator<Item = (&mut [u8], Range<usize>)>

Iterates over tuples of &mut [u8] slices and associated Range describing this slice position in the whole SgList.

pub unsafe fn iter_masked<'a>(     &'a self,     mask: Range<usize> ) -> impl Iterator<Item = iovec> + 'a

Given a mask iterates over iovec that a visible after masking
