Package: effect
Module: Exit

Exit.filterSuccess

Extracts the Success variant from an Exit as a Result.

When to use

Use when composing Exit checks with Filter or other Result-based filtering APIs and you want the full Success wrapper.

Details

Returns Result.succeed(success) when the Exit is a Success, or Result.fail(failure) with the original Failure otherwise.

Gotchas

This is not an Option accessor or an Effect failure. A failed extraction is represented as data in the Result failure channel.

Example (Filtering for success)

import { Exit, Result } from "effect"

const exit = Exit.succeed(42)
const result = Exit.filterSuccess(exit)

console.log(Result.isSuccess(result)) // true

See

• filterFailure for the inverse
• filterValue to extract the raw value instead of the Success object

Signature

declare const filterSuccess: <A, E>(self: Exit<A, E>) => Result.Result<Success<A>, Failure<never, E>>
