TimingSectionHandler

rustc_errors::timings

Struct TimingSectionHandler 

Source 
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

Source

pub fn new(enabled: bool) -> Self

Source

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.

Source

pub fn start_section( &self, diag_ctxt: DiagCtxtHandle<'_>, section: TimingSection, )

Start the provided section.

Source

pub fn end_section(&self, diag_ctxt: DiagCtxtHandle<'_>, section: TimingSection)

End the provided section.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
