Index specification for advanced indexing

Variants

Int(isize)

Single integer index

Index(isize)

Single integer index (alias for compatibility)

Slice(Option<isize>, Option<isize>, Option<isize>)

Slice with start, stop, step

Array(Vec<usize>)

Array of indices (fancy indexing)

Indices(Vec<usize>)

Array of indices (alias for compatibility)

BoolMask(Vec<bool>)

Boolean mask

Mask(Vec<bool>)

Boolean mask (alias for compatibility)

All

Select all elements (equivalent to :)

Ellipsis

Ellipsis (…) - expand to fill remaining dimensions

NewAxis

New axis (None in NumPy)

Implementations

impl IndexSpec

pub fn from_range<R>(range: R, _axis_size: usize) -> Self

where R: Into<SliceInfo>,

pub fn resolve(&self, axis_size: usize) -> Result<ResolvedIndex>

Resolve the index specification to concrete indices
