rustc_errors::timings

Struct TimingSectionHandler

Source 
pub struct TimingSectionHandler {
    origin: Option<Instant>,
}
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.

Implementations§

Source§

impl TimingSectionHandler

Source

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