Struct PythonManagedObject 

pub struct PythonManagedObject {
    pub kind: PythonManagedKind,
    pub edges: Vec<ManagedId>,
}

Cyclic mutable Python payload held exclusively in the shared managed arena.

Fields

kind: PythonManagedKind

Language-visible allocation role; collection does not special-case it.

edges: Vec<ManagedId>

Strong links to other Python objects.

Trait Implementations

impl Clone for PythonManagedObject

fn clone(&self) -> PythonManagedObject

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PythonManagedObject

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PythonManagedObject

fn default() -> PythonManagedObject

Returns the “default value” for a type.

impl ManagedObject for PythonManagedObject

fn trace_edges(&self, visitor: &mut dyn EdgeVisitor)

Enumerates all strong, weak, and ephemeron edges exactly once.

fn clear_weak_edge(&mut self, _: EdgeId, _: ManagedId) -> bool

Clears one weak edge if it still points at expected.

fn clear_ephemeron_edge( &mut self, _: EdgeId, _: ManagedId, _: ManagedId, ) -> bool

Clears one ephemeron entry if it still has the expected key and value. Repeating a successful request must return false.
