RangeArgument is implemented by Rust's built-in range types, produced by range syntax like .., a.., ..b or c..d.

Required Methods

🔬 This is a nightly-only experimental API.   (collections_range)

waiting for dust to settle on inclusive ranges

Start index bound

Return start value as a Bound

Examples

#![feature(collections)]
#![feature(collections_range)]
#![feature(collections_bound)]

extern crate collections;

use collections::range::RangeArgument;
use collections::Bound::*;

assert_eq!((..10).start(), Unbounded);
assert_eq!((3..10).start(), Included(&3));

🔬 This is a nightly-only experimental API.   (collections_range)

End index bound

Return end value as a Bound

Examples

#![feature(collections)]
#![feature(collections_range)]
#![feature(collections_bound)]

extern crate collections;

use collections::range::RangeArgument;
use collections::Bound::*;

assert_eq!((3..).end(), Unbounded);
assert_eq!((3..10).end(), Excluded(&10));
