Struct core::ops::RangeFull 1.0.0[−][src]
pub struct RangeFull;
An unbounded range (..).
RangeFull is primarily used as a slicing index, its shorthand is ...
It cannot serve as an Iterator because it doesn't have a starting point.
Examples
The .. syntax is a RangeFull:
assert_eq!((..), std::ops::RangeFull);Run
It does not have an IntoIterator implementation, so you can't use it in
a for loop directly. This won't compile:
for i in .. { // ... }Run
Used as a slicing index, RangeFull produces the full array as a slice.
let arr = [0, 1, 2, 3]; assert_eq!(arr[ .. ], [0,1,2,3]); // RangeFull assert_eq!(arr[ ..3], [0,1,2 ]); assert_eq!(arr[1.. ], [ 1,2,3]); assert_eq!(arr[1..3], [ 1,2 ]);Run
