Struct DisjointMutPtr 

pub struct DisjointMutPtr<T>(/* private fields */);

A raw mutable pointer wrapper that implements Send and Sync.

Used to enable parallel writes to disjoint slices of a pre-allocated buffer from within closures that require Send + Sync (e.g. rayon::ParallelIterator::for_each_init).

Safety

The caller must ensure that concurrent accesses through this pointer always target non-overlapping memory regions.

Implementations

impl<T> DisjointMutPtr<T>

pub const fn new(slice: &mut [T]) -> Self

Create a new DisjointMutPtr from a mutable slice.

pub const unsafe fn slice_mut( self, offset: usize, len: usize, ) -> &'static mut [T]

Get a mutable slice starting at offset with len elements.

Safety

The caller must ensure the range [offset, offset+len) is within bounds and does not overlap with any other concurrent access.
