1//! Storage for the parser to expand macros call into.
2
3/// This storage is used by the parser to store the expaned content of a macro call. It is only
4/// used when user-defined macros are used. Otherwise, this storage is not used and is _zero-overhead_.
5///
6/// [`Storage`] needs to exist because Rust does not allow self-referencial types. When Rust does
7/// (hopefully) gain support for self-referencial types, this storage will be removed.
