}Expand description
Predicts how much of the young allocation in the coming cycle will survive.
Fields§
§alloc_vol: AtomicUsizeYoung allocation over the current cycle: the denominator of both ratios.
copy_promote_vol: AtomicUsizeVolume promoted by copying during the current cycle.
prev_copy_promote_ratio: Atomic<f64>Smoothed copy_promote_vol / alloc_vol over previous cycles.
promote_vol: AtomicUsizeVolume promoted by any means during the current cycle.
prev_promote_ratio: Atomic<f64>Smoothed promote_vol / alloc_vol over previous cycles.
