Implementations§

source§

impl MemBalancerStats

source

fn generational_mem_stats_on_gc_start<VM: VMBinding>( &mut self, _plan: &dyn GenerationalPlan<VM = VM> )

source

fn generational_mem_stats_on_gc_release<VM: VMBinding>( &mut self, plan: &dyn GenerationalPlan<VM = VM> )

source

fn generational_mem_stats_on_gc_end<VM: VMBinding>( &mut self, plan: &dyn GenerationalPlan<VM = VM> ) -> bool

Return true if we should compute a new heap limit. Only do so at the end of a mature GC

source

fn non_generational_mem_stats_on_gc_release<VM: VMBinding>( &mut self, mmtk: &'static MMTK<VM> )
