impl<'tcx> MirPass<'tcx> for InstrumentCoverage

fn is_enabled(&self, sess: &Session) -> bool

Returns true if this pass is enabled with the current combination of compiler flags.

fn run_pass(&self, tcx: TyCtxt<'tcx>, mir_body: &mut Body<'tcx>)

fn name(&self) -> Cow<'_, str>

fn phase_change(&self) -> Option<MirPhase>

If this pass causes the MIR to enter a new phase, return that phase.

fn is_mir_dump_enabled(&self) -> bool

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.
