Struct StridedSliceSpec 

pub struct StridedSliceSpec { /* private fields */ }

One-axis slice specification for typed view slicing.

This follows ndarray’s range-with-step model: negative start or end values count from the end of the axis, end is exclusive, and negative step reverses the selected range before stepping.

Examples

use tenferro_tensor::StridedSliceSpec;

let every_other_reversed = StridedSliceSpec::new(0, None, -2);
assert_eq!(every_other_reversed.step(), -2);

Implementations

impl StridedSliceSpec

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

Create a slice from a signed start, optional exclusive end, and step.

Examples

use tenferro_tensor::StridedSliceSpec;

let slice = StridedSliceSpec::new(1, Some(-1), 1);
assert_eq!(slice.start(), 1);
assert_eq!(slice.end(), Some(-1));

pub fn all() -> Self

Select the full axis.

Examples

use tenferro_tensor::StridedSliceSpec;

assert_eq!(StridedSliceSpec::all(), StridedSliceSpec::new(0, None, 1));

pub fn reverse() -> Self

Select the full axis in reverse order.

Examples

use tenferro_tensor::StridedSliceSpec;

assert_eq!(StridedSliceSpec::reverse(), StridedSliceSpec::new(0, None, -1));

pub fn start(&self) -> isize

Return the signed start bound.

Examples

use tenferro_tensor::StridedSliceSpec;

assert_eq!(StridedSliceSpec::new(-3, None, 1).start(), -3);

pub fn end(&self) -> Option<isize>

Return the optional signed exclusive end bound.

Examples

use tenferro_tensor::StridedSliceSpec;

assert_eq!(StridedSliceSpec::new(0, Some(2), 1).end(), Some(2));

pub fn step(&self) -> isize

Return the signed step.

Examples

use tenferro_tensor::StridedSliceSpec;

assert_eq!(StridedSliceSpec::reverse().step(), -1);

Trait Implementations

impl Clone for StridedSliceSpec

fn clone(&self) -> StridedSliceSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for StridedSliceSpec

impl Debug for StridedSliceSpec

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

Formats the value using the given formatter.

impl Eq for StridedSliceSpec

impl PartialEq for StridedSliceSpec

fn eq(&self, other: &StridedSliceSpec) -> 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.
