Implementations§

source§

impl<'tcx> FunctionItemRefChecker<'_, 'tcx>

source

fn check_bound_args( &self, def_id: DefId, args_ref: GenericArgsRef<'tcx>, args: &[Spanned<Operand<'tcx>>], source_info: SourceInfo, )

Emits a lint for function reference arguments bound by fmt::Pointer in calls to the function defined by def_id with the generic parameters args_ref.

source

fn is_pointer_trait(&self, bound: Clause<'tcx>) -> Option<Ty<'tcx>>

If the given predicate is the trait fmt::Pointer, returns the bound parameter type.

source

fn is_fn_ref(ty: Ty<'tcx>) -> Option<(DefId, GenericArgsRef<'tcx>)>

If a type is a reference or raw pointer to the anonymous type of a function definition, returns that function’s DefId and GenericArgsRef.

source

fn nth_arg_span(&self, args: &[Spanned<Operand<'tcx>>], n: usize) -> Span

source

fn emit_lint( &self, fn_id: DefId, fn_args: GenericArgsRef<'tcx>, source_info: SourceInfo, span: Span, )

Trait Implementations§

source§

impl<'tcx> Visitor<'tcx> for FunctionItemRefChecker<'_, 'tcx>

source§

fn visit_terminator( &mut self, terminator: &Terminator<'tcx>, location: Location, )
