Trait core::ops::RangeArgument

pub trait RangeArgument<T: ?Sized> {
    fn start(&self) -> Bound<&T>;
    fn end(&self) -> Bound<&T>;
}

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

Required Methods

fn start(&self) -> Bound<&T>

Start index bound.

Returns the start value as a Bound.

Examples

use std::ops::RangeArgument;
use std::ops::Bound::*;

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

fn end(&self) -> Bound<&T>

End index bound.

Returns the end value as a Bound.

Examples

use std::ops::RangeArgument;
use std::ops::Bound::*;

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