Function unwrapThrow

unwrapThrow<R extends Result.Base>(
result: R,
toStr?: (e: UnwrapErr<R>) => string,
): UnwrapOk<R>
Unwraps a Result, returning the success value. Throws an error if the Result is Result.Err.

This is useful when you're confident that a Result should contain a success value and want to treat errors as exceptional conditions. The error message will be constructed from the error value using the provided string conversion function.
Type Parameters
- R extends Result.Base
  The Result.Base type to unwrap.
Parameters
- result: R
  The Result to unwrap.
- toStr: (e: UnwrapErr<R>) => string = toStr_
  An optional function to convert the error value to a string for the error message. Defaults to String.
Returns UnwrapOk<R>
The success value if Result.Ok.
Example
```
const okResult = Result.ok('data');
const errResult = Result.err(new Error('fail'));

assert(Result.unwrapThrow(okResult) === 'data');
assert.throws(() => Result.unwrapThrow(errResult), /fail/u);
```
Throws
Error with the stringified error value if the Result is Result.Err.
