Struct SliceRange 

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

A half-open range [start, stop) with a positive step.

Examples

use ipfrs_tensorlogic::slice_view::SliceRange;

let r = SliceRange { start: 0, stop: 10, step: 2 };
assert_eq!(r.len(), 5);
assert_eq!(r.indices(), vec![0, 2, 4, 6, 8]);

Fields

start: usize

First index to include.

stop: usize

Exclusive upper bound.

step: usize

Step between successive indices; must be ≥ 1 for a non-empty range.

Implementations

impl SliceRange

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

Create a new SliceRange with an explicit step.

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

Create a contiguous range [start, stop) with step = 1.

pub fn len(&self) -> usize

Number of elements produced by this range.

Returns 0 if step == 0 or start >= stop. Otherwise uses ceiling division: ⌈(stop − start) / step⌉.

pub fn is_empty(&self) -> bool

Returns true when the range contains no elements.

pub fn indices(&self) -> Vec<usize>

Materialise all indices: start, start+step, start+2*step, … while < stop.

Trait Implementations

impl Clone for SliceRange

fn clone(&self) -> SliceRange

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SliceRange

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SliceRange

fn default() -> Self

Returns the “default value” for a type.

impl Eq for SliceRange

impl PartialEq for SliceRange

fn eq(&self, other: &SliceRange) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
