Struct SliceSpec 

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

A slice specification for one axis, mirroring Python’s start:stop:step.

All fields are optional (represented by None), matching NumPy behaviour:

• start: defaults to 0 (or end-1 if step < 0)
• stop: defaults to size (or before-start if step < 0)
• step: defaults to 1; must not be 0

Fields

start: Option<isize>

Start index (inclusive). Negative counts from end.

stop: Option<isize>

Stop index (exclusive). Negative counts from end.

step: Option<isize>

Step size. Must not be zero.

Implementations

impl SliceSpec

pub fn full() -> Self

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

Create a slice start:stop with step 1.

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

Create a slice start:stop:step.
