Crate proc_macro2_impersonated

Adapted from proc-macro2 Removed wrap proc-macro for correct span outside rust sources Not use in proc-macro context if you don’t know what you do

A substitute implementation of the compiler’s proc_macro API

Thread-Safety

Most types in this crate are !Sync because the underlying compiler types make use of thread-local memory, meaning they cannot be accessed from a different thread.
