Implementations
Trait Implementations
sourceimpl Display for TokenTree
impl Display for TokenTree
Prints the token tree as a string that is supposed to be losslessly convertible back
into the same token tree (modulo spans), except for possibly TokenTree::Group
s
with Delimiter::None
delimiters and negative numeric literals.
