Enum IndexSpec 

pub enum IndexSpec {
    Index(usize),
    Slice(usize, Option<usize>, Option<usize>),
    Indices(Vec<usize>),
    Mask(Vec<bool>),
    All,
    Ellipsis,
    NewAxis,
}

Represents an index specification for a single dimension

Variants

Index(usize)

A single index

Slice(usize, Option<usize>, Option<usize>)

A range of indices with start, end, and optional step

Indices(Vec<usize>)

A set of arbitrary indices

Mask(Vec<bool>)

A boolean mask

All

All indices

Ellipsis

Ellipsis (…) - expands to the number of : needed for selection

NewAxis

NewAxis (np.newaxis) - inserts a new axis of length 1

Implementations

impl IndexSpec

pub fn slice(start: usize, end: Option<usize>, step: Option<usize>) -> Self

Create a new slice specification

pub fn from_range(range: Range<usize>) -> Self

Create a new index specification from a range

pub fn from_indices(indices: Vec<usize>) -> Self

Create a new index specification from a vector of indices

pub fn from_mask(mask: Vec<bool>) -> Self

Create a new index specification from a boolean mask

pub fn ellipsis() -> Self

Create an ellipsis index specification

pub fn newaxis() -> Self

Create a new axis index specification (inserts dimension of size 1)

Trait Implementations

impl Clone for IndexSpec

fn clone(&self) -> IndexSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.
