setunion Function

The setunion function takes multiple sets and produces a single set containing the elements from all of the given sets. In other words, it computes the union of the sets.

hcl
setunion(sets...)

Examples

shell-session
> setunion(["a", "b"], ["b", "c"], ["d"])
[
  "d",
  "b",
  "c",
  "a",
]

The given arguments are converted to sets, so the result is also a set and the ordering of the given elements is not preserved.

  • contains tests whether a given list or set contains a given element value.
  • setintersection computes the intersection of multiple sets.
  • setproduct computes the Cartesian product of multiple sets.
