Expand description

Implements the AST traversal for late lint passes. T provides the check_* methods.

Implementations§

source§

impl<'tcx, T: LateLintPass<'tcx>> LateContextAndPass<'tcx, T>

source

fn with_lint_attrs<F>(&mut self, id: HirId, f: F)
where F: FnOnce(&mut Self),

Merge the lints specified by any lint attributes into the current lint context, call the provided function, then reset the lints in effect to their previous state.

where F: FnOnce(&mut Self),

Trait Implementations§

source§

impl<'tcx, T: LateLintPass<'tcx>> Visitor<'tcx> for LateContextAndPass<'tcx, T>

source§

fn nested_visit_map(&mut self) -> Self::Map

Because lints are scoped lexically, we want to walk nested items in the context of the outer item, so enable deep-walking.

§

type NestedFilter = All

Override this type to control which nested HIR are visited; see NestedFilter for details. If you override this type, you must also override nested_visit_map. Read more
source§

fn visit_nested_body(&mut self, body_id: BodyId)

Invoked to visit the body of a function, method or closure. Like visit_nested_item, does nothing by default unless you override Self::NestedFilter.

source§

fn visit_body(&mut self, body: &'tcx Body<'tcx>)

source§

fn visit_item(&mut self, it: &'tcx Item<'tcx>)

Visits the top-level item and (optionally) nested items / impl items. See visit_nested_item for details.

§

type Map = <Self::NestedFilter as NestedFilter<'v>>::Map

§

type Result = ()

The result type of the visit_* methods. Can be either (), or ControlFlow<T>.
source§

fn visit_nested_item(&mut self, id: ItemId) -> Self::Result

Invoked when a nested item is encountered. By default, when Self::NestedFilter is nested_filter::None, this method does nothing. You probably don’t want to override this method – instead, override Self::NestedFilter or use the “shallow” or “deep” visit patterns described at rustc_hir::intravisit. The only reason to override this method is if you want a nested pattern but cannot supply a Map; see nested_visit_map for advice.
