Implementations

impl SelfProfilerRef

pub fn new(
    profiler: Option<Arc<SelfProfiler>>,
    print_verbose_generic_activities: bool,
    print_extra_verbose_generic_activities: bool
) -> SelfProfilerRef

fn exec<F>(&self, event_filter: EventFilter, f: F) -> TimingGuard<'_> where
    F: for<'a> FnOnce(&'a SelfProfiler) -> TimingGuard<'a>, 

pub fn verbose_generic_activity<'a>(
    &'a self,
    event_label: &'static str
) -> VerboseTimingGuard<'a>

Start profiling a verbose generic activity. Profiling continues until the VerboseTimingGuard returned from this call is dropped. In addition to recording a measureme event, “verbose” generic activities also print a timing entry to stdout if the compiler is invoked with -Ztime or -Ztime-passes.

pub fn extra_verbose_generic_activity<'a, A>(
    &'a self,
    event_label: &'static str,
    event_arg: A
) -> VerboseTimingGuard<'a> where
    A: Borrow<str> + Into<String>, 

Start profiling a extra verbose generic activity. Profiling continues until the VerboseTimingGuard returned from this call is dropped. In addition to recording a measureme event, “extra verbose” generic activities also print a timing entry to stdout if the compiler is invoked with -Ztime-passes.

pub fn generic_activity(&self, event_label: &'static str) -> TimingGuard<'_>

Start profiling a generic activity. Profiling continues until the TimingGuard returned from this call is dropped.

pub fn generic_activity_with_arg<A>(
    &self,
    event_label: &'static str,
    event_arg: A
) -> TimingGuard<'_> where
    A: Borrow<str> + Into<String>, 

Start profiling a generic activity. Profiling continues until the TimingGuard returned from this call is dropped.

pub fn generic_activity_with_args(
    &self,
    event_label: &'static str,
    event_args: &[String]
) -> TimingGuard<'_>

pub fn query_provider(&self) -> TimingGuard<'_>

Start profiling a query provider. Profiling continues until the TimingGuard returned from this call is dropped.

pub fn query_cache_hit(&self, query_invocation_id: QueryInvocationId)

Record a query in-memory cache hit.

pub fn query_blocked(&self) -> TimingGuard<'_>

Start profiling a query being blocked on a concurrent execution. Profiling continues until the TimingGuard returned from this call is dropped.

pub fn incr_cache_loading(&self) -> TimingGuard<'_>

Start profiling how long it takes to load a query result from the incremental compilation on-disk cache. Profiling continues until the TimingGuard returned from this call is dropped.

fn instant_query_event(
    &self,
    event_kind: fn(_: &SelfProfiler) -> StringId,
    query_invocation_id: QueryInvocationId,
    event_filter: EventFilter
)

pub fn with_profiler(&self, f: impl FnOnce(&SelfProfiler))

pub fn enabled(&self) -> bool

pub fn llvm_recording_enabled(&self) -> bool

pub fn get_self_profiler(&self) -> Option<Arc<SelfProfiler>>

Trait Implementations

impl Clone for SelfProfilerRef

fn clone(&self) -> SelfProfilerRef

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
