Struct StopMutators

pub struct StopMutators<C: GCWorkContext> {
    skip_mutator_roots: bool,
    flush_mutator: bool,
    phantom: PhantomData<C>,
}

Stop all mutators

TODO: Smaller work granularity

Fields

skip_mutator_roots: bool

If this is true, we skip creating ScanMutatorRoots work packets for mutators. By default, this is false.

flush_mutator: bool

Flush mutators once they are stopped. By default this is false. ScanMutatorRoots will flush mutators.

phantom: PhantomData<C>

Implementations

impl<C: GCWorkContext> StopMutators<C>

pub fn new() -> Self

pub fn new_no_scan_roots() -> Self

Create a StopMutators work packet that does not create ScanMutatorRoots work packets for mutators, and will simply flush mutators.

Trait Implementations

impl<C: Default + GCWorkContext> Default for StopMutators<C>

fn default() -> StopMutators<C>

Returns the “default value” for a type.

impl<C: GCWorkContext> GCWork<<C as GCWorkContext>::VM> for StopMutators<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.
