Struct mmtk::scheduler::gc_work::Prepare

pub struct Prepare<C: GCWorkContext> {
    pub plan: *const C::PlanType,
}

The global GC Preparation Work This work packet invokes prepare() for the plan (which will invoke prepare() for each space), and pushes work packets for preparing mutators and collectors. We should only have one such work packet per GC, before any actual GC work starts. We assume this work packet is the only running work packet that accesses plan, and there should be no other concurrent work packet that accesses plan (read or write). Otherwise, there may be a race condition.

Trait Implementations

impl<C: GCWorkContext> GCWork<<C as GCWorkContext>::VM> for Prepare<C>

fn do_work(&mut self, worker: &mut GCWorker<C::VM>, mmtk: &'static MMTK<C::VM>)

Define the work for this packet. However, this is not supposed to be called directly. Usually do_work_with_stat() should be used.

fn do_work_with_stat( &mut self, worker: &mut GCWorker<VM>, mmtk: &'static MMTK<VM> )

Do work and collect statistics. This internally calls do_work(). In most cases, this should be called rather than do_work() so that MMTk can correctly collect statistics for the work packets. If the feature “work_packet_stats” is not enabled, this call simply forwards the call to do_work().

fn get_type_name(&self) -> &'static str

Get the compile-time static type name for the work packet.
