pub struct LateContextAndPass<'tcx, T: LateLintPass<'tcx>> {
    context: LateContext<'tcx>,
    pass: T,
}
Expand description

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

Fields§

§context: LateContext<'tcx>§pass: T

Implementations§

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.

Trait Implementations§

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

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
Invoked to visit the body of a function, method or closure. Like visit_nested_item, does nothing by default unless you override Self::NestedFilter. Read more
Visits the top-level item and (optionally) nested items / impl items. See visit_nested_item for details. Read more
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 on itemlikevisit::ItemLikeVisitor. 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. Read more
Like visit_nested_item(), but for trait items. See visit_nested_item() for advice on when to override this method. Read more
Like visit_nested_item(), but for impl items. See visit_nested_item() for advice on when to override this method. Read more
Like visit_nested_item(), but for foreign items. See visit_nested_item() for advice on when to override this method. Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Performs the conversion.

Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
