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.
The .. syntax is a RangeFull:
It does not have an IntoIterator implementation, so you can't use it in a for loop directly. This won't compile:
Used as a slicing index, RangeFull produces the full array as a slice.
let arr = [0, 1, 2, 3, 4]; assert_eq!(arr[ .. ], [0,1,2,3,4]); // RangeFull assert_eq!(arr[ .. 3], [0,1,2 ]); assert_eq!(arr[ ..=3], [0,1,2,3 ]); assert_eq!(arr[1.. ], [ 1,2,3,4]); assert_eq!(arr[1.. 3], [ 1,2 ]); assert_eq!(arr[1..=3], [ 1,2,3 ]);

impl SliceIndex<str> for RangeFull[src]1.20.0
Implements substring slicing with syntax &self[..] or &mut self[..].
Returns a slice of the whole string, i.e., returns &self or &mut self. Equivalent to &self[0 .. len] or &mut self[0 .. len]. Unlike other indexing operations, this can never panic.
This operation is O(1).
Prior to 1.20.0, these indexing operations were still supported by direct implementation of Index and IndexMut.
Equivalent to &self[0 .. len] or &mut self[0 .. len].
type Output = strThe output type returned by methods.
