Trait for displaying an AST node’s content
Required Methods§
Sourcefn name() -> Option<&'static str>
fn name() -> Option<&'static str>
Name of the node

the name of the node type.
Sourcefn display_extra(&self, f: &mut Formatter<'_>) -> Result
fn display_extra(&self, f: &mut Formatter<'_>) -> Result
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.
