Function std.algorithm.mutation.fill

Assigns value to each element of input range range.

void fill(Range, Value) (
  auto ref Range range,
  auto ref Value value
)
if (isInputRange!Range && is(typeof(range.front = value)) || isSomeChar!Value && is(typeof(range[] = value)));

void fill(InputRange, ForwardRange) (
  InputRange range,
  ForwardRange filler
)
if (isInputRange!InputRange && (isForwardRange!ForwardRange || isInputRange!ForwardRange && isInfinite!ForwardRange) && is(typeof(InputRange.init.front = ForwardRange.init.front)));

Alternatively, instead of using a single value to fill the range, a filler forward range can be provided. The length of filler and range do not need to match, but filler must not be empty.

Parameters

NameDescription
range An input range that exposes references to its elements and has assignable elements
value Assigned to each element of range
filler A forward range representing the fill pattern.

Throws

If filler is empty.
