Trait RootKind

pub trait RootKind {
    type Vtable;

    const VTABLE: Self::Vtable;
    const KIND: RootKind;
}

A trait for JS types that can be registered as roots.

Required Associated Constants

const VTABLE: Self::Vtable

const KIND: RootKind

Required Associated Types

type Vtable

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
