Function std.algorithm.mutation.uninitializedFill

Initializes each element of range with value. Assumes that the elements of the range are uninitialized. This is of interest for structs that define copy constructors (for all other types, fill and uninitializedFill are equivalent).

void uninitializedFill(Range, Value) (
  Range range,
  Value value
if (isInputRange!Range && hasLvalueElements!Range && is(typeof(range.front = value)));


range An input range that exposes references to its elements and has assignable elements
value Assigned to each element of range
