Expand description
A matrix allocator of a memory buffer that may contain R::to_usize() * C::to_usize()
elements of type T
.
An allocator is said to be:
− static: if R
and C
both implement DimName
.
− dynamic: if either one (or both) of R
or C
is equal to Dynamic
.
Every allocator must be both static and dynamic. Though not all implementations may share the
same Buffer
type.
Associated Types
type Buffer: ContiguousStorageMut<T, R, C> + Clone
[src]
type Buffer: ContiguousStorageMut<T, R, C> + Clone
[src]The type of buffer this allocator can instanciate.

unsafe fn allocate_uninitialized(
nrows: R,
ncols: C
) -> MaybeUninit<Self::Buffer>
[src]Allocates a buffer with the given number of rows and columns without initializing its content.

I: IntoIterator<Item = T>,
[src]
fn allocate_from_iterator<I>(nrows: R, ncols: C, iter: I) -> Self::Buffer where
I: IntoIterator<Item = T>,
[src]Allocates a buffer initialized with the content of the given iterator.
