CLASHING_EXTERN_DECLARATIONS

The clashing_extern_declarations lint detects when an extern fn has been declared with the same name but different types.

Functions

clashing_extern_declarations 🔒

get_relevant_span 🔒

We want to ensure that we use spans for both decls that include where the name was defined, whether that was from the link_name attribute or not.

lint_vec 🔒

name_of_extern_decl 🔒

Get the name of the symbol that’s linked against for a given extern declaration. That is, the name specified in a #[link_name = …] attribute if one was specified, else, just the symbol’s name.

provide 🔒

structurally_same_type 🔒

Checks whether two types are structurally the same enough that the declarations shouldn’t clash. We need this so we don’t emit a lint when two modules both declare an extern struct, with the same members (as the declarations shouldn’t clash).

structurally_same_type_impl 🔒
