Module: HashSet

HashSet.mutate

Mutates the HashSet within the context of the provided function.

You can consider it a functional abstraction on top of the lower-level mutation primitives of module:HashSet.beginMutation -> mutable context -> HashSet.endMutation.

Example

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

// with data-last, a.k.a. pipeable API
pipe(
  HashSet.make(1, 2, 3),
  HashSet.mutate((set) => {
    HashSet.add(set, 4)
    HashSet.remove(set, 1)
  })
)

// or piped with the pipe function
HashSet.make(1, 2, 3).pipe(
  HashSet.mutate((set) => {
    HashSet.add(set, 4)
    HashSet.remove(set, 1)
  })
)

// or with data-first API
HashSet.mutate(HashSet.make(1, 2, 3), (set) => {
  HashSet.add(set, 4)
  HashSet.remove(set, 1)
})
