    function_coverage_info: &'tcx FunctionCoverageInfo,
    is_used: bool,
    counters_seen: BitSet<CounterId>,
    zero_expressions: ZeroExpressions,
}

Fields

is_used: bool

counters_seen: BitSet<CounterId>

zero_expressions: ZeroExpressions

Implementations

impl<'tcx> FunctionCoverage<'tcx>

pub(crate) fn is_used(&self) -> bool

Returns true for a used (called) function, and false for an unused function.

pub(crate) fn source_hash(&self) -> u64

Return the source hash, generated from the HIR node structure, and used to indicate whether or not the source code structure changed between different compilations.

pub(crate) fn all_file_names( &self, ) -> impl Iterator<Item = Symbol> + Captures<'_>

Returns an iterator over all filenames used by this function’s mappings.

pub(crate) fn counter_expressions( &self, ) -> impl Iterator<Item = CounterExpression> + ExactSizeIterator + Captures<'_>

Convert this function’s coverage expression data into a form that can be passed through FFI to LLVM.

pub(crate) fn counter_regions( &self, ) -> impl Iterator<Item = (MappingKind, &SourceRegion)> + ExactSizeIterator

Converts this function’s coverage mappings into an intermediate form that will be used by mapgen when preparing for FFI.

fn counter_for_term(&self, term: CovTerm) -> Counter

fn is_zero_term(&self, term: CovTerm) -> 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.
