Function repeat

Create a range which repeats one value.

Repeat!T repeat(T) (
  T value
);

Take!(Repeat!T) repeat(T) (
  T value,
  size_t n
);

Parameters

NameDescription
value the value to repeat
n the number of times to repeat value

Returns

If n is not defined, an infinite random access range with slicing.

If n is defined, a random access range with slicing.

Example

import std.algorithm.comparison : equal;

assert(5.repeat().take(4).equal([5, 5, 5, 5]));

Example

import std.algorithm.comparison : equal;

assert(5.repeat(4).equal([5, 5, 5, 5]));

Parameters

NameDescription
value the value to repeat
n the number of times to repeat value

Returns
