[−][src]Trait nshare::MutNdarray2

pub trait MutNdarray2 {
    type Out;
    pub fn mut_ndarray2(self) -> Self::Out;
}

Mutably 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.
