Struct rustc_middle::mir::query::CoverageInfo
source · Expand description
Coverage information summarized from a MIR if instrumented for source code coverage (see
compiler option -Cinstrument-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
.

default fn fingerprint_style() -> FingerprintStyle
sourcedefault fn to_fingerprint(&self, tcx: Ctxt) -> Fingerprint
default fn to_fingerprint(&self, tcx: Ctxt) -> Fingerprint
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

sourcedefault fn recover(Ctxt, &DepNode<<Ctxt as DepContext>::DepKind>) -> Option<T>
default fn recover(Ctxt, &DepNode<<Ctxt as DepContext>::DepKind>) -> Option<T>
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 moresourceimpl<T, R> InternIteratorElement<T, R> for T

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
