Struct PythonHeap 

pub struct PythonHeap { /* private fields */ }

Python managed heap composed from the shared arena and optional collector.

Implementations

impl PythonHeap

pub fn standard( cap: usize, limits: CollectionLimits, ) -> Result<Self, ArenaError>

Create the standard tracing heap.

pub fn retaining(cap: usize) -> Result<Self, ArenaError>

Create the explicit no-collector heap whose cycle leak is reported by cycle_leak_gap.

pub fn allocate( &mut self, value: PythonManagedObject, ) -> Result<ManagedHandle, ArenaError>

Allocate a cyclic-capable value only in the managed arena.

pub fn connect( &mut self, from: ManagedHandle, to: ManagedHandle, ) -> Result<(), ArenaError>

Add a strong language edge between two managed values.

pub fn live_len(&self) -> usize

Return the number of live managed allocations.

pub const fn policy(&self) -> PythonHeapPolicy

Return selected policy.

pub const fn cycle_leak_gap(&self) -> Option<&'static str>

Return the explicit retention gap, if selected.

pub fn collect(&mut self) -> Result<Option<CollectionReceipt>, CollectionError>

Run a safepoint. Retention performs no implicit collection.
