size_type mtl::irange::from_range

(

size_type

i

const [inline]

Maps integers [start(), finish()) to [0, size()).

Checks index in debug mode.

size_type mtl::irange::to_range

(

size_type

i

)

const [inline]

Maps integers [0, size()) to [start(), finish()).

Checks index in debug mode. Inverse of from_range.
