Struct scale_info::prelude::ops::RangeToInclusive
1.26.0 · source · [−]pub struct RangeToInclusive<Idx> {
pub end: Idx,
}Expand description
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 });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 {
// ...
}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, 4];
assert_eq!(arr[ .. ], [0, 1, 2, 3, 4]);
assert_eq!(arr[ .. 3], [0, 1, 2 ]);
assert_eq!(arr[ ..=3], [0, 1, 2, 3 ]); // This is a `RangeToInclusive`
assert_eq!(arr[1.. ], [ 1, 2, 3, 4]);
assert_eq!(arr[1.. 3], [ 1, 2 ]);
assert_eq!(arr[1..=3], [ 1, 2, 3 ]);Fields
end: IdxThe upper bound of the range (inclusive)

Implements substring slicing with syntax &self[..= end] or &mut self[..= end].
Returns a slice of the given string from the byte range [0, end].
Equivalent to &self [0 .. end + 1], except if end has the maximum
value for usize.
This operation is O(1).
Panics
Panics if end does not point to the ending byte offset of a character
(end + 1 is either a starting byte offset as defined by
is_char_boundary, or equal to len), or if end >= len.
