Struct syn::buffer::TokenBuffer

pub struct TokenBuffer { /* fields omitted */ }

A buffer that can be efficiently traversed multiple times, unlike TokenStream which requires a deep copy in order to traverse more than once.

See the module documentation for an example of TokenBuffer in action.

This type is available if Syn is built with the "parsing" feature.
