Struct rustc_middle::mir::CoverageInfo[][src]

pub struct CoverageInfo {
    pub num_counters: u32,
    pub num_expressions: u32,
}

Coverage information summarized from a MIR if instrumented for source code coverage (see compiler option -Zinstrument-coverage). This information is generated by the InstrumentCoverage MIR pass and can be retrieved via the coverageinfo query.

Fields

num_counters: u32

The total number of coverage region counters added to the MIR Body.

num_expressions: u32

The total number of coverage region counter expressions added to the MIR Body.
