Trait ndarray::SliceArg

pub unsafe trait SliceArg<D: Dimension>: AsRef<[SliceInfoElem]> {
    type OutDim: Dimension;

    fn in_ndim(&self) -> usize;
    fn out_ndim(&self) -> usize;
}

A type that can slice an array of dimension D.

This trait is unsafe to implement because the implementation must ensure that D, Self::OutDim, self.in_dim(), and self.out_ndim() are consistent with the &[SliceInfoElem] returned by self.as_ref() and that self.as_ref() always returns the same value when called multiple times.

Required Associated Types

type OutDim: Dimension

Dimensionality of the output array.

Required Methods

fn in_ndim(&self) -> usize

Returns the number of axes in the input array.

fn out_ndim(&self) -> usize

Returns the number of axes in the output array.
