Module std::range

Integer ranges

Ranges come in different flavors, depending on what kind of bounds they have. For example 0..3 (Range) is a range that contains numbers 0, 1 and 2, 0..=3 (RangeInclusive) is a range that contains numbers 0, 1, 2 and 3.

The most common use of ranges is in for loops and in slice indexing.

There are also some other places where ranges are used in the standard library (e.g. next for generating random numbers).

See also Range and RangeOf for protocols that can be used for designing APIs that accept generic ranges.
