Trait rin::math::base::allocator::Allocator

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

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

pub 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.

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

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