Trait Rootable

source 
pub trait Rootable: Sized + Traceable {
    const VTABLE: RootedVFTable = _;

    // Provided method
    unsafe extern "C" fn trace(
        this: *mut c_void,
        trc: *mut JSTracer,
        _name: *const i8,
    ) { ... }
}
Expand description

Marker trait that allows any type that implements the [trace::Traceable] trait to be used with the Rooted type.

Rooted<T> relies on dynamic dispatch in C++ when T uses the Traceable RootKind. This trait initializes the vtable when creating a Rust instance of the Rooted object.

Provided Associated Constants§

Object Safety§
