Source 
pub trait EdgeVisitor {
    // Required methods
    fn strong(&mut self, edge: EdgeId, target: ManagedId);

    fn ephemeron(&mut self, edge: EdgeId, key: ManagedId, value: ManagedId);
}

Required Methods§

Source

fn strong(&mut self, edge: EdgeId, target: ManagedId)

Visits a retaining edge.

Source

fn weak(&mut self, edge: EdgeId, target: ManagedId)

Visits a non-retaining edge that may be cleared after tracing.

Source

fn ephemeron(&mut self, edge: EdgeId, key: ManagedId, value: ManagedId)
