Required methods

pub fn create_pgo_func_name_var(&self, instance: Instance<'tcx>) -> Self::Value[src]

pub fn set_function_source_hash(
    &mut self,
    instance: Instance<'tcx>,
    function_source_hash: u64
) -> bool[src]

Returns true if the function source hash was added to the coverage map (even if it had already been added, for this instance). Returns false only if -Z instrument-coverage is not enabled (a coverage map is not being generated).

pub fn add_coverage_counter(
    &mut self,
    instance: Instance<'tcx>,
    index: CounterValueReference,
    region: CodeRegion
) -> bool[src]

Returns true if the counter was added to the coverage map; false if -Z instrument-coverage is not enabled (a coverage map is not being generated).

pub fn add_coverage_counter_expression(
    &mut self,
    instance: Instance<'tcx>,
    id: InjectedExpressionId,
    lhs: ExpressionOperandId,
    op: Op,
    rhs: ExpressionOperandId,
    region: Option<CodeRegion>
) -> bool[src]

Returns true if the expression was added to the coverage map; false if -Z instrument-coverage is not enabled (a coverage map is not being generated).

pub fn add_coverage_unreachable(
    &mut self,
    instance: Instance<'tcx>,
    region: CodeRegion
) -> bool[src]

Returns true if the region was added to the coverage map; false if -Z instrument-coverage is not enabled (a coverage map is not being generated).
