match<A> method

A match<A>(
  1. A ok(
    1. T t
    ),
  2. A err(
    1. E e
    )
)

Given 2 functions (one for the Ok variant and one for the Err variant) execute the function that matches the Result variant.

Match callbacks do not necessitate to return a Result, however you can return a Result if you want to.

match is like chaining map and mapErr, with the distinction that with match both functions must have the same return type.
