std.algorithm.setops.set_symmetric_difference - multiple declarations

Function setSymmetricDifference

Lazily computes the symmetric difference of r1 and r2, i.e. the elements that are present in exactly one of r1 and r2. The two ranges are assumed to be sorted by less, and the output is also sorted by less. The element types of the two ranges must have a common type.

If both arguments are ranges of L-values of the same type then SetSymmetricDifference will also be a range of L-values of that type.

Prototype

SetSymmetricDifference!(less,R1,R2) setSymmetricDifference(alias less, R1, R2)(
  R1 r1,
  R2 r2
);

Parameters

NameDescription
less Predicate the given ranges are sorted by.
r1 The first range.
r2 The second range.

Returns

A range of the symmetric difference between r1 and r2.

Example

import std.algorithm.comparison : equal;

int[] a = [ 1, 2, 4, 5, 7, 9 ];
int[] b = [ 0, 1, 2, 4, 7, 8 ];
assert(equal(setSymmetricDifference(a, b), [0, 5, 8, 9][]));
static assert(isForwardRange!(typeof(setSymmetricDifference(a, b))));
