Struct core::ops::RangeToInclusive 1.26.0[−][src]
pub struct RangeToInclusive<Idx> {
pub end: Idx,
}A range only bounded inclusively above (..=end).
The RangeToInclusive ..=end contains all values with x <= end.
It cannot serve as an Iterator because it doesn't have a starting point.
Examples
The ..=end syntax is a RangeToInclusive:
assert_eq!((..=5), std::ops::RangeToInclusive{ end: 5 });Run
It does not have an IntoIterator implementation, so you can't use it in a
for loop directly. This won't compile:
// error[E0277]: the trait bound `std::ops::RangeToInclusive<{integer}>: // std::iter::Iterator` is not satisfied for i in ..=5 { // ... }Run
When used as a slicing index, RangeToInclusive produces a slice of all
array elements up to and including the index indicated by end.
let arr = [0, 1, 2, 3]; assert_eq!(arr[ ..=2], [0,1,2 ]); // RangeToInclusive assert_eq!(arr[1..=2], [ 1,2 ]);Run
Fields
end: Idx
The upper bound of the range (inclusive)
