}Expand description
A trait for types that exist in the AST.
Implementations of this type are generally generated via macro.
Required Methods§
Sourcefn cast(node: &NodeOrToken) -> Option<Self>where
Self: Sized,
fn cast(node: &NodeOrToken) -> Option<Self>where
Self: Sized,
Attempt to cast from some node or token to this type.
