[][src]Trait nalgebra::base::allocator::Allocator

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
