Expand description

A range with a size that may be known at compile-time.

This may be:

  • A single usize index, e.g., 4
  • A left-open range std::ops::RangeTo, e.g., .. 4
  • A right-open range std::ops::RangeFrom, e.g., 4 ..
  • A full range std::ops::RangeFull, e.g., ..

Required Associated Types§

source

type Size: Dim

Type of the range size. May be a type-level integer.

Required Methods§

source

fn begin(&self, shape: D) -> usize

The start index of the range.

source

fn end(&self, shape: D) -> usize

The index immediately after the last index inside of the range.

source

fn size(&self, shape: D) -> Self::Size

The number of elements of the range, i.e., self.end - self.begin.
