Struct gluon_vm::gc::Gc

pub struct Gc { /* fields omitted */ }

A mark and sweep garbage collector.

Methods

impl Gc

fn new(generation: Generation, memory_limit: usize) -> Gc

Constructs a new garbage collector

fn set_memory_limit(&mut self, memory_limit: usize)

fn generation(&self) -> Generation

fn new_child_gc(&self) -> Gc

unsafe fn alloc_and_collect<R, D>(&mut self,
                                  roots: R,
                                  def: D)
                                  -> Result<GcPtr<D::Value>> where R: Traverseable, D: DataDef + Traverseable, D::Value: Sized + Any

Allocates a new object. If the garbage collector has hit the collection limit a collection will occur.

Unsafe since roots must be able to traverse all accesible GcPtr values.

fn alloc<D>(&mut self, def: D) -> Result<GcPtr<D::Value>> where D: DataDef, D::Value: Sized + Any

Allocates a new object.

fn alloc_ignore_limit<D>(&mut self, def: D) -> GcPtr<D::Value> where D: DataDef, D::Value: Sized + Any

unsafe fn check_collect<R>(&mut self, roots: R) -> bool where R: Traverseable

unsafe fn collect<R>(&mut self, roots: R) where R: Traverseable

Does a mark and sweep collection by walking from roots. This function is unsafe since roots need to cover all reachable object.

fn mark<T: ?Sized>(&mut self, value: GcPtr<T>) -> bool

Marks the GcPtr Returns true if the pointer was already marked

Trait Implementations

impl Debug for Gc

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
