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

pub fn size(&self) -> usize

Returns number of elements in the underlying object, NOT the total number of bytes.

pub fn is_empty(&self) -> bool

Does this sg list has any element?

pub unsafe fn capacity(&self) -> usize

Calculates the total amount of bytes in this SgList

Trait Implementations

impl PartialEq<SgList> for SgList

fn eq(&self, other: &SgList) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &SgList) -> bool

This method tests for !=.

impl Sync for SgList

impl Clone for SgList

fn clone(&self) -> SgList

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Send for SgList

impl<O> From<SgList> for SgData<O> where
    O: Clone, 

fn from(sglist: SgList) -> Self

Performs the conversion.

impl Debug for SgList

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Serialize for SgList

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for SgList

fn deserialize<D>(_deserializer: D) -> Result<Self, D::Error> where
    D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.
