pub trait RefNdarray2 {
type Out;
// Required method
fn ref_ndarray2(self) -> Self::Out;
}Expand description
Borrows a 2d type to a ndarray 2d array type.
Coordinates are in (row, col).
This uses an associated type to avoid ambiguity for the compiler. By calling this, the compiler always knows the returned type.
