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>
🔬 This is a nightly-only experimental API. (collections_range #30877)
waiting for dust to settle on inclusive ranges
Start index bound.
Returns the start value as a Bound.
Examples
#![feature(alloc)] #![feature(collections_range)] extern crate alloc; use alloc::range::RangeArgument; use alloc::Bound::*; assert_eq!((..10).start(), Unbounded); assert_eq!((3..10).start(), Included(&3));
fn end(&self) -> Bound<&T>
🔬 This is a nightly-only experimental API. (collections_range #30877)
waiting for dust to settle on inclusive ranges
End index bound.
Returns the end value as a Bound.
Examples
#![feature(alloc)] #![feature(collections_range)] extern crate alloc; use alloc::range::RangeArgument; use alloc::Bound::*; assert_eq!((3..).end(), Unbounded); assert_eq!((3..10).end(), Excluded(&10));
