Function std.algorithm.mutation.uninitializedFill
Initializes each element of rangevaluerange are uninitialized.
This is of interest for structs that
define copy constructors (for all other types, fill and
uninitializedFill are equivalent).
Prototype
void uninitializedFill(Range, Value)( Range range, Value value ) if (isInputRange!Range && hasLvalueElements!Range && is(typeof(range.front = value)));
Parameters
| Name | Description |
|---|---|
| range | An input range that exposes references to its elements and has assignable elements |
| value | Assigned to each element of range |

Example
struct S { ... }
S[] s = (cast(S*) malloc(5 * S.sizeof))[0 .. 5];
uninitializedFill(s, 42);
assert(s == [ 42, 42, 42, 42, 42 ]);
