Struct SliceRange 

pub struct SliceRange {
    pub start: usize,
    pub stop: usize,
    pub step: usize,
}

A range specification for one axis when slicing a tensor.

Mirrors Python’s start:stop:step slice notation.

Examples

let r = SliceRange::new(0, 10, 2); // 0, 2, 4, 6, 8
assert_eq!(r.start, 0);
assert_eq!(r.step, 2);

Fields

start: usize

stop: usize

step: usize

Implementations

impl SliceRange

pub fn new(start: usize, stop: usize, step: usize) -> Self

Create a new slice range.

Panics

Panics in debug mode if step == 0.

Examples

let r = SliceRange::new(1, 5, 2);
assert_eq!(r.start, 1);
assert_eq!(r.stop, 5);

pub fn range(start: usize, stop: usize) -> Self

Shorthand for start..stop with step 1.

Examples

let r = SliceRange::range(2, 5);
assert_eq!(r.step, 1);

pub fn full(len: usize) -> Self

Select the full extent of an axis. Requires knowing the axis length.

Examples

let r = SliceRange::full(5);
assert_eq!(r.start, 0);
assert_eq!(r.stop, 5);
assert_eq!(r.step, 1);
