Enum js::jsapi::AllowGC

#[repr(u32)]
pub enum AllowGC {
    NoGC,
    CanGC,
}

Types for a variable that either should or shouldn't be rooted, depending on the template parameter allowGC. Used for implementing functions that can operate on either rooted or unrooted data.

The toHandle() and toMutableHandle() functions are for calling functions which require handle types and are only called in the CanGC case. These allow the calling code to type check.
