Function fromThrowable

fromThrowable<T>(fn: () => T): Result<T, Error>
Wraps a function that may throw an exception in a Result.

This is a fundamental utility for converting traditional exception-based error handling into Result-based error handling. Any thrown value is converted to an Error object for consistent error handling.

If the function executes successfully, returns Result.Ok with the result. If the function throws, returns Result.Err with the caught error.
Type Parameters
- T
  The return type of the function.
Parameters
- fn: () => T
  The function to execute that may throw.
Returns Result<T, Error>
A Result<T, Error> containing either the successful result or the caught error.
Example
```
const success = Result.fromThrowable(() => 1 + 1);
const failure = Result.fromThrowable(() => {
  throw new Error('boom');
});

assert.deepStrictEqual(success, Result.ok(2));
assert.ok(Result.isErr(failure));
```
