Remarks

This type is publicly immutable, but internally mutable. It is only populated by the descriptor parsing code - by the time any user code is able to see an instance, it will be fully initialized.

If an option is requested using the incorrect method, an answer may still be returned: all of the numeric types are represented internally using 64-bit integers, for example. It is up to the caller to ensure that they make the appropriate method call for the option they're interested in. Note that enum options are simply stored as integers, so the value should be fetched using TryGetInt32(int, out int) and then cast appropriately.

Repeated options are currently not supported. Asking for a single value of an option which was actually repeated will return the last value, except for message types where all the set values are merged together.
