Struct sgx_tstd::ops::RangeFull

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);

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 .. {
   // ...
}

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  ]);
