Trait nalgebra::core::allocator::Allocator
[−]
[src]
pub trait Allocator<N: Scalar, R: Dim, C: Dim = U1>: Any + Sized { type Buffer: ContiguousStorageMut<N, R, C> + Clone; unsafe fn allocate_uninitialized(nrows: R, ncols: C) -> Self::Buffer; fn allocate_from_iterator<I: IntoIterator<Item = N>>(
nrows: R,
ncols: C,
iter: I
) -> Self::Buffer; }
A matrix allocator of a memory buffer that may contain R::to_usize() * C::to_usize()
elements of type N
.
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<N, R, C> + Clone
The type of buffer this allocator can instanciate.
Required Methods
unsafe fn allocate_uninitialized(nrows: R, ncols: C) -> Self::Buffer
Allocates a buffer with the given number of rows and columns without initializing its content.
fn allocate_from_iterator<I: IntoIterator<Item = N>>(
nrows: R,
ncols: C,
iter: I
) -> Self::Buffer
nrows: R,
ncols: C,
iter: I
) -> Self::Buffer
Allocates a buffer initialized with the content of the given iterator.
