Feature Flags

Features enabled by default are marked with *.

• multithread: Enables support for accessing the registry from multiple threads. This adds a bound that all registered types must be Send.
• derive (*): Enables support for the #[derive(Inject)] macro.
• tokio: Enables support for async constructors. Bumps the MSRV up to 1.75.0 because some of the internal traits require RPITIT.
• tracing: Enables support for tracing and annotates all public functions with tracing::instrument.
