Function std.range.padRight

Extend the length of the input range r by padding out the end of the range with the element e. The element e must be of a common type with the element type of the range r as defined by CommonType. If n is less than the length of of r, then the contents of r are returned.

auto auto padRight(R, E) (
  R r,
  E e,
  size_t n
)
if (isInputRange!R && !isInfinite!R && !is(CommonType!(ElementType!R, E) == void));

The range primitives that the resulting range provides depends whether or not r provides them. Except the functions back and popBack, which also require the range to have a length as well as back and popBack

Parameters

NameDescription
r an input range with a length
e element to pad the range with
n the length to pad to

Returns

A range containing the elements of the original range with the extra padding

Example

import std.algorithm.comparison : equal;

assert([1, 2, 3, 4].padRight(0, 6).equal([1, 2, 3, 4, 0, 0]));
assert([1, 2, 3, 4].padRight(0, 4).equal([1, 2, 3, 4]));

assert("abc".padRight('_', 6).equal("abc___"));
