Function canonicalize_index

pub fn canonicalize_index<Index>(
    idx: Index,
    size: usize,
    wrap_scalar: bool,
) -> usize
where
    Index: AsIndex,
Expand description

Canonicalizes and bounds checks an index with negative indexing support.

§Arguments

  • idx - The index to canonicalize.
  • size - The size of the index range.
  • wrap_scalar - If true, pretend scalars have rank=1.

§Returns

The canonicalized dimension index.

§Panics

  • If wrap_scalar is false and the tensor has no dimensions.
  • If the dimension index is out of range.
