expect

function ResultAsync.expect(
    result: AwaitableResult<T, E>,
    message: string
): Promise<T>

Unwraps the Ok value from the result. If the result is an Err, throws a ResultError with the given message.

Example

data-first

await ResultAsync.expect(ok(5), "Expected a value");
// 5

await ResultAsync.expect(err("fail"), "Expected a value");
// throws ResultError("Expected a value")

data-last

await pipe(ok(5), ResultAsync.expect("Expected a value"));
// 5
