Struct Slice 

pub struct Slice {
    pub start: Option<isize>,
    pub stop: Option<isize>,
    pub step: isize,
}

A Python-style slice: start:stop:step. Negative indices count from the end.

Fields

start: Option<isize>

First index. None is the start of the axis (the end for a negative step).

stop: Option<isize>

Index after the last one. None is past the end of the axis.

step: isize

Distance between indices. Negative steps go backward. Zero is an error.

Implementations

impl Slice

pub fn new(start: Option<isize>, stop: Option<isize>, step: isize) -> Self

A slice start:stop:step.

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

start..stop with step 1.

pub fn step(step: isize) -> Self

::step.

pub fn full() -> Self

The whole axis, :.

pub fn resolve(&self, len: usize) -> Result<(usize, usize, isize)>

Resolve against an axis of len: (first index, count, step), like slice.indices.
