Package: effect
Module: HashSet

HashSet.isSubset

Returns true if and only if every element in the this HashSet is an element of the second set,

NOTE: the hash and equal of both sets must be the same.

Time complexity analysis is of O(n)

Example

// Syntax
import { HashSet, pipe } from "effect"

const set1 = HashSet.make(0, 1)
const set2 = HashSet.make(1, 2)
const set3 = HashSet.make(0, 1, 2)

// with `data-last`, a.k.a. `pipeable` API
pipe(set1, HashSet.isSubset(set2)) // false
pipe(set1, HashSet.isSubset(set3)) // true

// or piped with the pipe function
set1.pipe(HashSet.isSubset(set2)) // false
set1.pipe(HashSet.isSubset(set3)) // true

// or with `data-first` API
HashSet.isSubset(set1, set2) // false
HashSet.isSubset(set1, set3) // true)
