Package: effect
Module: Struct

Struct.pick

Creates a new struct containing only the specified keys.

When to use

Use to narrow a struct down to a subset of its properties.

Gotchas

Keys not present in the struct are silently ignored.

Example (Selecting specific properties)

import { pipe, Struct } from "effect"

const user = { name: "Alice", age: 30, admin: true }
const nameAndAge = pipe(user, Struct.pick(["name", "age"]))
console.log(nameAndAge) // { name: "Alice", age: 30 }

See

• omit – the inverse (exclude keys instead)
• get – extract a single value

Signature

declare const pick: { <S extends object, const Keys extends ReadonlyArray<keyof S>>(keys: Keys): (self: S) => Simplify<Pick<S, Keys[number]>>; <S extends object, const Keys extends ReadonlyArray<keyof S>>(self: S, keys: Keys): Simplify<Pick<S, Keys[number]>>; }
