match

function ResultAsync.match(
    result: AwaitableResult<T, E>,
    patterns: {
        Ok: (value: T) => U | Promise<U>,
        Err: (error: E) => F | Promise<F>
    }
): Promise<U | F>

Pattern matches on the result using the provided patterns object. Calls the Ok function if the result is Ok, or the Err function if the result is an Err.

Example

data-first

await ResultAsync.match(ok(5), {
    Ok: (x) => `Value: ${x}`,
    Err: (e) => `Error: ${e}`,
});
// "Value: 5"

await ResultAsync.match(err("fail"), {
    Ok: (x) => `Value: ${x}`,
    Err: (e) => `Error: ${e}`,
});
// "Error: fail"

data-last

await pipe(
    ok(5),
    ResultAsync.match({
        Ok: (x) => `Value: ${x}`,
        Err: (e) => `Error: ${e}`,
    }),
);
// "Value: 5"
