Struct rustc_middle::mir::query::CoverageInfo

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.

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
