Sourcefn declared_names(&self) -> Vec<Ident>
fn declared_names(&self) -> Vec<Ident>
All of the names (items) declared by this node. This is an approximation and should only be used for diagnostics.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
