flip

function Result.flip(result: Result<T, E>): Result<E, T>

Swaps the Ok and Err values of the result. An Ok becomes an Err and an Err becomes an Ok.

Example

data-first

Result.flip(ok(5));
// Err<number>(5)

Result.flip(err("fail"));
// Ok<string>("fail")

data-last

pipe(ok(5), Result.flip());
// Err<number>(5)
