Struct MutView 

pub struct MutView<'a, B: BufferMut + ?Sized> { /* private fields */ }

A writable receive buffer that scatters incoming bytes into a base buffer according to a UserDatatype layout. Mirrors rsmpi’s MutView.

Implementations

impl<'a, B: BufferMut + ?Sized> MutView<'a, B>

pub fn with_count( buf: &'a mut B, datatype: UserDatatype, count: Count, ) -> MutView<'a, B>

Create a mutable view of count elements of datatype over buf.

Trait Implementations

impl<B: BufferMut + ?Sized> BufferMut for MutView<'_, B>

fn as_bytes_mut(&mut self) -> &mut [u8]

A mutable byte view of the whole buffer.

fn scatter_from(&mut self, bytes: &[u8])

Place received bytes into this buffer.

impl<B: BufferMut + ?Sized> Collection for MutView<'_, B>

fn count(&self) -> Count

Number of elements.

fn as_datatype(&self) -> DatatypeRef

The datatype of the elements.
