fn is_joint(&self) -> bool

Punct spacing is Joint

Other return false when self is not Punct

fn as_punct_char(&self) -> Option<char>

fn tt(self) -> TokenTree

Into TokenTree, like TokenTree::from(self)

fn unit_stream(self) -> TokenStream

TokenStream::from_iter(self.tt())

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.
