Struct rustc_middle::mir::CoverageInfo [−][src]
Expand description
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
.

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous). Read more
This method tries to recover the query key from the given DepNode
,
something which is needed when forcing DepNode
s during red-green
evaluation. The query system will only call this method if
fingerprint_style()
is not FingerprintStyle::Opaque
.
It is always valid to return None
here, in which case incremental
compilation will treat the query as having changed instead of forcing it. Read more
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.
