Trait MaybeResPath 

pub trait MaybeResPath<'a>: Copy {
    // Required method
    fn opt_res_path(self) -> (Option<&'a Ty<'a>>, Option<&'a Path<'a>>);

    // Provided methods
    fn basic_res(self) -> &'a Res { ... }
    fn res_local_id(self) -> Option<HirId> { ... }
    fn res_local_id_and_ident(self) -> Option<(HirId, &'a Ident)> { ... }
}

A HIR node which might be a QPath::Resolved.

The following are resolved paths:

• A path to a module or crate item.
• A path to a trait item via the trait’s name.
• A path to a struct or variant constructor via the original type’s path.
• A local.

All other paths are TypeRelative and require using PathRes to lookup the resolution.

Required Methods

fn opt_res_path(self) -> (Option<&'a Ty<'a>>, Option<&'a Path<'a>>)

If this node is a resolved path gets both the contained path and the type associated with it.

Provided Methods

fn basic_res(self) -> &'a Res

If this node is a resolved path gets it’s resolution. Returns Res::Err otherwise.

fn res_local_id(self) -> Option<HirId>

If this node is a path to a local gets the local’s HirId.

fn res_local_id_and_ident(self) -> Option<(HirId, &'a Ident)>

If this node is a path to a local gets the local’s HirId and identifier.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
