[−][src]Struct rexsgdata::SgList
Wrapper for a C-style scatter gather list
Methods
impl SgList
[src]
pub fn new(iovec: *const iovec, count: usize) -> Self
[src]
Constructs new SgList
object from raw arguments
pub fn into_inner(self) -> (*const iovec, usize)
[src]
Deconstructs the SgList
object into original building blocks.
pub unsafe fn index_unchecked(&self, idx: isize) -> &iovec
[src]
Returns a reference to a idx
' element of this Scatter Gather List
pub unsafe fn iter(&self) -> impl Iterator<Item = &iovec>
[src]
Iterates over &iovec
stored in this SgList
pub unsafe fn iter_slices(&self) -> impl Iterator<Item = &[u8]>
[src]
Iterates over byte slices &u8
pub unsafe fn iter_slices_mut(&self) -> impl Iterator<Item = &mut [u8]>
[src]
Iterates over byte slices &u8
pub unsafe fn iter_range(&self) -> impl Iterator<Item = (&iovec, Range<usize>)>
[src]
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>)>
[src]
&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>)>
[src]
&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
[src]
&'a self,
mask: Range<usize>
) -> impl Iterator<Item = iovec> + 'a
Given a mask
iterates over iovec
that a visible after masking
pub fn size(&self) -> usize
[src]
Returns number of elements in the underlying object, NOT the total number of bytes.
pub fn is_empty(&self) -> bool
[src]
Does this sg list has any element?
pub unsafe fn capacity(&self) -> usize
[src]
Calculates the total amount of bytes in this SgList
