Trait nalgebra::base::allocator::Allocator

pub trait Allocator<T: Scalar, R: Dim, C: Dim = U1>: Any + Sized {
    type Buffer: ContiguousStorageMut<T, R, C> + Clone;
    unsafe fn allocate_uninitialized(
        nrows: R, 
        ncols: C
    ) -> MaybeUninit<Self::Buffer>;
    fn allocate_from_iterator<I: IntoIterator<Item = T>>(
        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 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

The type of buffer this allocator can instanciate.

Required methods

unsafe fn allocate_uninitialized(
    nrows: R,
    ncols: C
) -> MaybeUninit<Self::Buffer>

Allocates a buffer with the given number of rows and columns without initializing its content.

fn allocate_from_iterator<I: IntoIterator<Item = T>>(
    nrows: R,
    ncols: C,
    iter: I
) -> Self::Buffer

Allocates a buffer initialized with the content of the given iterator.
