A single token or a delimited sequence of token trees (e.g.,
[1, (), ..]).
A token stream surrounded by bracket delimiters.
A single punctuation character (
A literal character (
'a'), string (
"hello"), number (
Returns the span of this tree, delegating to the
span method of
the contained token or a delimited stream.
Configures the span for only this token.
Note that if this token is a
Group then this method will not configure
the span of each of the internal tokens, this will simply delegate to
set_span method of each variant.
Prints token tree in a form convenient for debugging.
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
Delimiter::None delimiters and negative numeric literals.
