pub fn claim_warning_once(&self, key: &'static str) -> bool

Returns true the first time it is called with key, so that a warning is reported once.

pub fn record_live_modifier_slice_lookup_miss(&self)

Counts one pointer dispatch that fell back to the captured modifier slices because the live node could not be found.

pub fn live_modifier_slice_lookup_miss_count(&self) -> usize
