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.
The bug was about instantiating a module with elements segment being out-of-bounds, however, it was with zero length. E.g.:
```
(module
(table 0 anyfunc)
(elem (i32.const 1))
)
```
In our impl there was no out-of-bounds, because there was no attempt to set any table entry.
This change adds early check for specifically this case.
