Struct mpi::datatype::PartitionMut

pub struct PartitionMut<'b, B: 'b + ?Sized, C, D> { /* fields omitted */ }

Adds a partitioning to an existing BufferMut so that it becomes Partitioned

Methods

impl<'b, B: ?Sized, C, D> PartitionMut<'b, B, C, D> where
    B: 'b + BufferMut,
    C: Borrow<[Count]>,
    D: Borrow<[Count]>, 

pub fn new(buf: &mut B, counts: C, displs: D) -> PartitionMut<B, C, D>

Partition buf using counts and displs
