match

function Result.match(result: Result<T, E>, patterns: {
    Ok: (value: T) => A
    Err: (error: E) => B
}): A | B

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

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

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

data-last

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