#[repr(C)]
pub struct Handle<T> {
    pub _base: HandleBase<T>,
    pub ptr: *const T,
}

[−] Expand description

Reference to a T that has been rooted elsewhere. This is most useful as a parameter type, which guarantees that the T lvalue is properly rooted. See "Move GC Stack Rooting" above.

If you want to add additional methods to Handle for a specific specialization, define a HandleBase specialization containing them.

Fields

_base: HandleBase<T>

ptr: *const T
