source · [−]pub struct Group { /* private fields */ }
Expand description
A delimited token stream.
A Group
internally contains a TokenStream
which is surrounded by
Delimiter
s.
Implementations
sourceimpl Group
impl Group
sourcepub fn new(delimiter: Delimiter, stream: TokenStream) -> Self
pub fn new(delimiter: Delimiter, stream: TokenStream) -> Self
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.
sourcepub fn stream(&self) -> TokenStream
pub fn stream(&self) -> TokenStream
Returns the TokenStream
of tokens that are delimited in this Group
.
Note that the returned token stream does not include the delimiter returned above.
sourcepub fn span(&self) -> Span
pub fn span(&self) -> Span
Returns the span for the delimiters of this token stream, spanning the
entire Group
.
pub fn span(&self) -> Span {
^^^^^^^
sourcepub fn span_open(&self) -> Span
pub fn span_open(&self) -> Span
Returns the span pointing to the opening delimiter of this group.
pub fn span_open(&self) -> Span {
^
sourcepub fn span_close(&self) -> Span
pub fn span_close(&self) -> Span
Returns the span pointing to the closing delimiter of this group.
pub fn span_close(&self) -> Span {
