Struct Frames 

pub struct Frames {
    pub layout: Layout,
    pub count: usize,
    /* private fields */
}

The frames of several arguments to a function of their trailing axes, such as a matrix function of the last two: the result’s frame, as broadcasting pairs the arguments’ frames, its number of cells, and each argument’s cell under each of them.

Fields

layout: Layout

count: usize

Implementations

impl Frames

pub fn new(args: &[(&Layout, usize)]) -> Result<Self, Error>

Pairs the frames of args, each a layout with the number of trailing axes in one of its cells. A Rank error where a layout has fewer axes than its cell, and a Length error where frames don’t agree, or where keyed frames would need a cell that an argument lacks.

pub fn one() -> Self

The frames of arguments that are one cell each, with no frame axes: one cell, which each argument’s only cell fills. It allocates nothing.

pub fn cell(&self, k: usize, i: usize) -> usize

Argument k’s cell under position i of the result’s frame. An argument with no list of cells, as in Frames::one or where its frame is the result’s, has the result’s cell.

pub fn items(&self, k: usize, i: usize, per: usize) -> Range<usize>

The positions of the per items of argument k’s cell under position i of the result’s frame, in an argument that holds its cells in order.
