Package: effect
Module: Option

Option.getSuccess

Converts a Result into an Option, keeping only the success value.

When to use

Use when you need to discard a Result failure and keep only the success value as an Option.

Details

• Success becomes Some with the success value
• Failure becomes None and the failure value is discarded

Example (Extracting the success side)

import { Option, Result } from "effect"

console.log(Option.getSuccess(Result.succeed("ok")))
// Output: { _id: 'Option', _tag: 'Some', value: 'ok' }

console.log(Option.getSuccess(Result.fail("err")))
// Output: { _id: 'Option', _tag: 'None' }

See

• getFailure for the opposite operation.

Signature

declare const getSuccess: <A, E>(self: Result<A, E>) => Option<A>
