Struct RootedVFTable

#[repr(C)]
pub struct RootedVFTable {
    pub padding: [usize; 2],
    pub trace: unsafe extern "C" fn(this: *mut c_void, trc: *mut JSTracer, name: *const c_char),
}

A vtable for use in RootedTraceable, which must be present for stack roots using RootKind::Traceable. The C++ tracing implementation uses a virtual trace function which is only present for C++ Rooted values that use the Traceable root kind.

Fields

padding: [usize; 2]

trace: unsafe extern "C" fn(this: *mut c_void, trc: *mut JSTracer, name: *const c_char)
