Expand description

Track the callstacks of allocations.

Fields§

§stochastic_rate: usize

Sample every N allocations. Must be power-of-two.

§readable_backtraces: IntMap<BacktraceHash, ReadableBacktrace>

De-duplicated readable backtraces.

§live_allocs: HashMap<PtrHash, BacktraceHash>

Current live allocations.

§callstack_stats: IntMap<BacktraceHash, CountAndSize>

How much memory is allocated by each callstack?

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
