pub struct TimingSectionHandler {
origin: Option<Instant>,
opened_sections: Lock<FxHashSet<TimingSection>>,
}
Expand description
Manages emission of start/end section timings, enabled through --json=timings
.
Fields§
§origin: Option<Instant>
Time when the compilation session started.
If None
, timing is disabled.
opened_sections: Lock<FxHashSet<TimingSection>>
Sanity check to ensure that we open and close sections correctly.
Implementations§
Source§impl TimingSectionHandler
impl TimingSectionHandler
pub fn new(enabled: bool) -> Self
Sourcepub fn section_guard<'a>(
&self,
diag_ctxt: DiagCtxtHandle<'a>,
section: TimingSection,
) -> TimingSectionGuard<'a>
pub fn section_guard<'a>( &self, diag_ctxt: DiagCtxtHandle<'a>, section: TimingSection, ) -> TimingSectionGuard<'a>
Returns a RAII guard that will immediately emit a start the provided section, and then emit its end when it is dropped.
Sourcepub fn start_section(
&self,
diag_ctxt: DiagCtxtHandle<'_>,
section: TimingSection,
)
pub fn start_section( &self, diag_ctxt: DiagCtxtHandle<'_>, section: TimingSection, )
Start the provided section.
Sourcepub fn end_section(&self, diag_ctxt: DiagCtxtHandle<'_>, section: TimingSection)
pub fn end_section(&self, diag_ctxt: DiagCtxtHandle<'_>, section: TimingSection)
End the provided section.
