mightrix

The mightrix crate exposes matrix types that let continuous memory be used as if it were a matrix. The dimensions of the matrix, if not heap allocated, asserted through const generics. This way the owned variant of the matrix Stacktrix can use a fixed size array on the stack. For the heap allocated Matrix the dimensions are provided in the constructor.

Example

use mightrix::{ Reftrix, ColumnPrio, ColumnPrioMatrix };

fn main() {
    let mut data = vec![1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 4];

    let mut matrix = Reftrix::<4, 4, ColumnPrio, u8>::from_values(&mut data[..]);

    for el in matrix.get_mut_row(0) {
        *el *= 2;
    }


    for col in matrix.cols_mut() {
        for (i, cell) in col.into_iter().enumerate() {
            *cell += i as u8;
        }
    }
    assert_eq!(&data[..], &[2, 2, 3, 4, 4, 3, 4, 5, 6, 4, 5, 6, 8, 5, 6, 7]);
}
