#[repr(C)]
pub struct Mat<E>where

    __marker: PhantomData<E>,
}

Expand description

Heap allocated resizable matrix, similar to a 2D Vec.

§Note

The memory layout of Mat is guaranteed to be column-major, meaning that it has a row stride of 1, and an unspecified column stride that can be queried with Mat::col_stride.

This implies that while each individual column is stored contiguously in memory, the matrix as a whole may not necessarily be contiguous. The implementation may add padding at the end of each column when overaligning each column can provide a performance gain.

Let us consider a 3×4 matrix

 0 │ 3 │ 6 │  9
───┼───┼───┼───
 1 │ 4 │ 7 │ 10
───┼───┼───┼───
 2 │ 5 │ 8 │ 11

The memory representation of the data held by such a matrix could look like the following:

0 1 2 X 3 4 5 X 6 7 8 X 9 10 11 X

where X represents padding elements.
