<A>(a: A): Exit<A>Creates a successful Exit containing the given value.
When to use
Use when you need an Exit that contains a known success value.
Details
Returns a Success<A> with the provided value. Does not perform any
computation.
Example (Creating a successful Exit)
import { Exit } from "effect"
const exit = Exit.succeed(42)
console.log(Exit.isSuccess(exit)) // trueexport const const succeed: <A>(a: A) => Exit<A>Creates a successful Exit containing the given value.
When to use
Use when you need an Exit that contains a known success value.
Details
Returns a Success<A> with the provided value. Does not perform any
computation.
Example (Creating a successful Exit)
import { Exit } from "effect"
const exit = Exit.succeed(42)
console.log(Exit.isSuccess(exit)) // true
succeed: <function (type parameter) A in <A>(a: A): Exit<A>A>(a: Aa: function (type parameter) A in <A>(a: A): Exit<A>A) => type Exit<A, E = never> = Success<A, E> | Failure<A, E>Represents the result of an Effect computation.
When to use
Use when you need to synchronously inspect whether an Effect computation
succeeded or failed.
Details
An Exit<A, E> is either Success<A, E> containing a value of type A, or
Failure<A, E> containing a Cause<E> describing why the computation
failed.
Since Exit is also an Effect, you can yield it inside Effect.gen.
Example (Pattern matching on an Exit)
import { Exit } from "effect"
const success: Exit.Exit<number> = Exit.succeed(42)
const failure: Exit.Exit<number, string> = Exit.fail("error")
const result = Exit.match(success, {
onSuccess: (value) => `Got value: ${value}`,
onFailure: (cause) => `Got error: ${cause}`
})
Namespace containing helper types shared by Exit values.
When to use
Use to reference helper types that describe the shared structure of Exit
values.
Exit<function (type parameter) A in <A>(a: A): Exit<A>A> = import corecore.const exitSucceed: <A>(
a: A
) => Exit.Exit<A>
