Casts have arithmetic semantics, and under some build configurations
Rust will panic when encountering an arithmetic overflow.
Use a transmute instead since it's what we mean.
The previous code worked, but still I added a test for good measure.
* Refactor TryInto → FromRuntimeValue.
Replace `TryInto<T, E>` with `FromRuntimeValue`.
The main difference is that `FromRuntimeValue` is implemented for the concrete type of the value we create, rather than on `RuntimeValue`. This makes more sense to me and seems more clear.
The `try_into` method is now implemented on `RuntimeValue` itself.
And finally, `FromRuntimeValue` has been made public.
* Impl AsRef<[RuntimeValue]> for RuntimeArgs
This impl can be used as an escape hatch if the user wants to use the inner slice.
* Little doc fixes for RuntimeArgs.
Fixes#63
Fix is simple: all labels refered by the br_table instruction must have same value type (or NoResult in case if they don't have result). So we just take the default label and check other labels against it.
