Struct proc_macro2::Group[][src]

pub struct Group { /* fields omitted */ }

A delimited token stream.

A Group internally contains a TokenStream which is surrounded by Delimiters.

Methods

impl Group
[src]

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 delimiter of this Group

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.

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.
