Struct jrsonnet_gcmodule::ThreadedObjectSpace

pub struct ThreadedObjectSpace { /* private fields */ }

A collection of tracked ThreadedCc objects that can be garbage collected.

ThreadedObjectSpace is similar to ObjectSpace but works with multi-thread.

Implementations

impl ThreadedObjectSpace

pub fn count_tracked(&self) -> usize

Count objects tracked by this ThreadedObjectSpace.

pub fn collect_cycles(&self) -> usize

Collect cyclic garbage tracked by this ThreadedObjectSpace. Return the number of objects collected.

pub fn create<T: Trace + Send + Sync>(&self, value: T) -> ThreadedCc<T>

Constructs a new ThreadedCc<T> in this ThreadedObjectSpace.

The returned object should not refer to ThreadedCc<T> created by a different ThreadedObjectSpace. Otherwise the collector might fail to collect cycles.

The type T needs to be Send + Sync. This is because the ThreadedObjectSpace is Send and Sync. The collector can run in a different thread to access ThreadedCc<T>, which needs to be Send + Sync to be safely accessed by the collector.

use gcmodule::{ThreadedObjectSpace, ThreadedCc, Cc};
let cc = Cc::new(5);
let space = ThreadedObjectSpace::default();
let tcc: ThreadedCc<Cc<_>> = space.create(cc);
