Package: effect
Module: Option

Option.zipRight

Sequences two Options, keeping the value from the second if both are Some.

When to use

Use when you need two Option values to both be Some, then keep only the second value.

Details

• Both Some → returns that
• Either None → returns None

Example (Keeping the second value)

import { Option } from "effect"

console.log(Option.zipRight(Option.some(1), Option.some("hello")))
// Output: { _id: 'Option', _tag: 'Some', value: 'hello' }

console.log(Option.zipRight(Option.none(), Option.some("hello")))
// Output: { _id: 'Option', _tag: 'None' }

See

• zipLeft to keep the first value instead
• zipWith to combine both values

Signature

declare const zipRight: { <B>(that: Option<B>): <_>(self: Option<_>) => Option<B>; <X, B>(self: Option<X>, that: Option<B>): Option<B>; }
