Struct proc_macro::Group 1.29.0[−][src]
pub struct Group(_);Expand description
A delimited token stream.
A Group internally contains a TokenStream which is surrounded by Delimiters.
Implementations
Creates a new Group with the given delimiter and token stream.
This constructor will set the span for this group to
Span::call_site(). To change the span you can use the set_span
method below.
Returns the TokenStream of tokens that are delimited in this Group.
Note that the returned token stream does not include the delimiter returned above.
Returns the span for the delimiters of this token stream, spanning the
entire Group.
pub fn span(&self) -> Span {
^^^^^^^Returns the span pointing to the opening delimiter of this group.
pub fn span_open(&self) -> Span {
^Returns the span pointing to the closing delimiter of this group.
pub fn span_close(&self) -> Span {
^Trait Implementations
Prints the group as a string that should be losslessly convertible back
into the same group (modulo spans), except for possibly TokenTree::Groups
with Delimiter::None delimiters.
