Implementations§

impl<'tcx> FunctionCoverage<'tcx>
sourcepub(crate) fn is_used(&self) -> bool
pub(crate) fn is_used(&self) -> bool
Returns true for a used (called) function, and false for an unused function.
sourcepub(crate) fn source_hash(&self) -> u64
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.
sourcepub(crate) fn all_file_names(
&self,
) -> impl Iterator<Item = Symbol> + Captures<'_>
pub(crate) fn all_file_names( &self, ) -> impl Iterator<Item = Symbol> + Captures<'_>
Returns an iterator over all filenames used by this function’s mappings.
sourcepub(crate) fn counter_expressions(
&self,
) -> impl Iterator<Item = CounterExpression> + ExactSizeIterator + Captures<'_>
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.
sourcepub(crate) fn counter_regions(
&self,
) -> impl Iterator<Item = (MappingKind, &SourceRegion)> + ExactSizeIterator
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.
