std.algorithm.setops.set_difference - multiple declarations
- Function setDifference
- Struct SetDifference
Function setDifference
Lazily computes the difference of r1r2less. The element types of the two
ranges must have a common type.
Prototype
SetDifference!(less,R1,R2) setDifference(alias less, R1, R2)( R1 r1, R2 r2 );
Parameters
| Name | Description |
|---|---|
| less | Predicate the given ranges are sorted by. |
| r1 | The first range. |
| r2 | The range to subtract from |
Returns

Example
import std.algorithm.comparison : equal; int[] a = [ 1, 2, 4, 5, 7, 9 ]; int[] b = [ 0, 1, 2, 4, 7, 8 ]; assert(equal(setDifference(a, b), [5, 9][])); static assert(isForwardRange!(typeof(setDifference(a, b))));
Struct SetDifference
Lazily computes the difference of r1 and r2. The two ranges
are assumed to be sorted by less. The element types of the two
ranges must have a common type.
Parameters
| Name | Description |
|---|---|
| less | Predicate the given ranges are sorted by. |
| r1 | The first range. |
| r2 | The range to subtract from r1. |
Returns
A range of the difference of r1 and r2.
