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`.
