Crate tor_persist 

tor-persist

Persistent data storage for use with Tor.

This crate is part of Arti, a project to implement Tor in Rust.

For now, users should construct storage objects directly with (for example) FsStateMgr::from_path_and_mistrust(), but use them primarily via the interfaces of the StateMgr trait.
