proc-macro2 • 1.0.89A substitute implementation of the compiler's `proc_macro` API to decouple token-based libraries from the procedural macro use case.
regex • 1.7.3An implementation of regular expressions for Rust. This implementation uses
finite automata and guarantees linear time matching on all inputs.
