Trait rin::math::base::allocator::Reallocator

pub trait Reallocator<N, RFrom, CFrom, RTo, CTo>: Allocator<N, RFrom, CFrom> + Allocator<N, RTo, CTo> where
    N: Scalar,
    RTo: Dim,
    CTo: Dim,
    RFrom: Dim,
    CFrom: Dim, {
    pub unsafe fn reallocate_copy(
        nrows: RTo, 
        ncols: CTo, 
        buf: Self::Buffer
    ) -> Self::Buffer;
}

A matrix reallocator. Changes the size of the memory buffer that initially contains (RFrom × CFrom) elements to a smaller or larger size (RTo, CTo).

Required methods

pub unsafe fn reallocate_copy(
    nrows: RTo,
    ncols: CTo,
    buf: Self::Buffer
) -> Self::Buffer

Reallocates a buffer of shape (RTo, CTo), possibly reusing a previously allocated buffer buf. Data stored by buf are linearly copied to the output:

• The copy is performed as if both were just arrays (without a matrix structure).
• If buf is larger than the output size, then extra elements of buf are truncated.
• If buf is smaller than the output size, then extra elements of the output are left uninitialized.
