[1, (), ..]).
A token stream surrounded by bracket delimiters.
A single punctuation character (
A literal character (

Returns the span of this tree, delegating to the

Group then this method will not configure

set_span method of each variant.

impl From<TokenTree> for TokenStream[src]
Creates a token stream containing a single token tree.
impl Extend<TokenTree> for TokenStream1.30.0[src]
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.
impl FromIterator<TokenTree> for TokenStream[src]
Collects a number of token trees into a single stream.
