Group - proc

`impl Group`

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.

fn delimiter(self: &Self) -> Delimiter

Returns the punctuation used as the delimiter for this group: a set of parentheses, square brackets, or curly braces.

fn stream(self: &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.

fn span(self: &Self) -> Span

Returns the span for the delimiters of this token stream, spanning the entire Group.

pub fn span(&self) -> Span {
           ^^^^^^^

fn span_open(self: &Self) -> Span

Returns the span pointing to the opening delimiter of this group.

pub fn span_open(&self) -> Span {
                ^

fn span_close(self: &Self) -> Span

Returns the span pointing to the closing delimiter of this group.

pub fn span_close(&self) -> Span {
                       ^

fn delim_span(self: &Self) -> DelimSpan

Returns an object that holds this group's span_open() and span_close() together (in a more compact representation than holding those 2 spans individually).

fn set_span(self: &mut Self, span: Span)

Configures the span for this Group's delimiters, but not its internal tokens.

This method will not set the span of all the internal tokens spanned by this group, but rather it will only set the span of the delimiter tokens at the level of the Group.
