transformTry

transformTry<T, U>(x, s, f): TryPromise<U> extends Promise<Try<_P>> ? Promise<Try<_P>> : TryPromise<U> extends Try<_V> ? Try<_V> : Try<TryPromise<U>>

This transform takes a function for either a Success or a Failure value. Depending on the state of the Try, it will apply the correct transformation and give back the result.

Any thrown exceptions during the transformation will be caught and set as Failure value.

Example

transformTry("foobar", s => `${s}${s}`, f => `failure`)
// => "foobarfoobar"

transformTry(new Error("foobar"), s => `${s}${s}`, f => `failure`)
// => "failure"

Type Parameters

• T extends unknown

The input type.

• U

The transformed type.

Parameters

x

s

(e) => TryPromise<U>

f

(e) => TryPromise<U>

Returns

TryPromise<U> extends Promise<Try<_P>> ? Promise<Try<_P>> : TryPromise<U> extends Try<_V> ? Try<_V> : Try<TryPromise<U>>

The transformed Try.
