Fields§

§current_trait_assoc_items: Option<&'ast [P<AssocItem>]>

The current trait’s associated items’ ident, used for diagnostic suggestions.

§current_self_type: Option<Ty>

The current self type if inside an impl (used for better errors).

§current_self_item: Option<NodeId>

The current self item if inside an ADT (used for better errors).

§current_item: Option<&'ast Item>

The current trait (used to suggest).

§currently_processing_generic_args: bool

When processing generic arguments and encountering an unresolved ident not found, suggest introducing a type or const param depending on the context.

§current_function: Option<(FnKind<'ast>, Span)>

The current enclosing (non-closure) function (used for better errors).

§unused_labels: FxHashMap<NodeId, Span>

A list of labels as of yet unused. Labels will be removed from this map when they are used (in a break or continue statement)

§current_block_could_be_bare_struct_literal: Option<Span>

Only used for better errors on let x = { foo: bar };. In the case of a parse error with let x = { foo: bar, };, this isn’t needed, it’s only needed for cases where this parses as a correct type ascription.

§current_let_binding: Option<(Span, Option<Span>, Option<Span>)>

Only used for better errors on let <pat>: <expr, not type>;.

§current_pat: Option<&'ast Pat>§in_if_condition: Option<&'ast Expr>

Used to detect possible if let written without let and to provide structured suggestion.

§in_assignment: Option<&'ast Expr>

Used to detect possible new binding written without let and to provide structured suggestion.

§is_assign_rhs: bool§in_range: Option<(&'ast Expr, &'ast Expr)>

Used to detect possible . -> .. typo when calling methods.

§current_trait_object: Option<&'ast [GenericBound]>

If we are currently in a trait object definition. Used to point at the bounds when encountering a struct or enum.

§current_where_predicate: Option<&'ast WherePredicate>

Given where <T as Bar>::Baz: String, suggest where T: Bar<Baz = String>.

§current_type_path: Option<&'ast Ty>§current_impl_items: Option<&'ast [P<AssocItem>]>

The current impl items (used to suggest).

§currently_processing_impl_trait: Option<(TraitRef, Ty)>

When processing impl trait

§current_elision_failures: Vec<MissingLifetime>

Accumulate the errors due to missed lifetime elision, and report them all at once for each function.
