pub struct RootCollection {
roots: UnsafeCell<Vec<*const dyn JSTraceable>>,
}Expand description
A rooting mechanism for reflectors on the stack. LIFO is not required.

§roots: UnsafeCell<Vec<*const dyn JSTraceable>>Implementations§
source§impl RootCollection
impl RootCollection
sourcepub fn new() -> RootCollection
pub fn new() -> RootCollection
Create an empty collection of roots
sourceunsafe fn root(&self, object: *const dyn JSTraceable)
unsafe fn root(&self, object: *const dyn JSTraceable)
Starts tracking a trace object.
sourceunsafe fn unroot(&self, object: *const dyn JSTraceable)
unsafe fn unroot(&self, object: *const dyn JSTraceable)
Stops tracking a trace object, asserting if it isn’t found.
