Neo4j Driver for Rust

Disclaimer:

  • While I'm currently affiliated with Neo4j, this is my private hobby project. It's not an officially supported piece of software by Neo4j.
  • This is a work in progress, and it's mostly developed in my spare time.
  • This project is primarily meant for private studies. Yet, I decided to publish it as it might be useful for others as well.

MSRV

Currently, this crate's minimum supported Rust version is 1.70. A bump in MSRV is considered a minor breaking change.

Note on async

Currently, there are no plans to add async support until a proper abstraction over multiple runtimes is available so that users can choose their preferred runtime. As it stands, the async ecosystem would either force this crate to dictate a runtime or do an ugly dance to support multiple runtimes. Even then, the supported runtimes would be limited to the ones chosen by this crate.
