Struct rustc_data_structures::profiling::SelfProfilerRef

pub struct SelfProfilerRef {
    profiler: Option<Arc<SelfProfiler>>,
    event_filter_mask: EventFilter,
    print_verbose_generic_activities: bool,
    print_extra_verbose_generic_activities: bool,
}

A reference to the SelfProfiler. It can be cloned and sent across thread boundaries at will.

Fields

event_filter_mask: EventFilter

print_verbose_generic_activities: bool

print_extra_verbose_generic_activities: bool

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.

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
