Struct GcScopeState 

pub struct GcScopeState<'heap> { /* private fields */ }

Implementations

impl<'heap> GcScopeState<'heap>

pub fn new(heap: &'heap mut GcHeap, partition_id: GcPartitionId) -> Self

pub fn partition_id(&self) -> GcPartitionId

pub fn heap(&self) -> &GcHeap

pub fn heap_mut(&mut self) -> &mut GcHeap

pub fn depth(&self) -> u8

pub fn count(&self) -> usize

pub fn parent(&self) -> Option<(&GcScopeState<'_>, u8)>

get parent scope, and its level.

pub fn alloc_root<T: GcNode>( &self, payload: T, ) -> Result<GcRef<T>, (GcError, T)>

pub fn alloc_local<T: GcNode>( &self, payload: T, ) -> Result<GcRef<T>, (GcError, T)>

alloc a local node in scope.

pub fn add_non_local(&self, node: NonNull<GcHead>) -> bool

pub fn get_promote(&self) -> Option<NonNull<GcHead>>

pub fn set_promote(&self, node: Option<NonNull<GcHead>>)

Set a node to be promoted.

Promote means when the scope is dropped, the node will be added to upper scope.

pub fn flush(&self)

clear and unprotect cached nodes. this behaves like to drop current scope, and start a new scope.

pub fn contains(&self, node: NonNull<GcHead>) -> bool
