Introduction

more-di-axum is a crate which provides dependency injection (DI) extensions for the axum web framework. Any trait or struct can be used as an injected service.

axum provides a dependency injection example; however, it is very limited. axum does not have, nor provide, a fully-fledged DI framework. State in axum must support Clone and is copied many times within the pipeline. In particular, the native State model does not intrinsically support a scoped (e.g. per-request) lifetime. This is a limitation of Clone. A state can be wrapped in Arc as a singleton; otherwise, it is transient. more-di-axum brings full support for various lifetimes by layering over the more-di library and makes them ergonomic to consume within axum. Since more-di is a complete DI framework, swapping out dependency registration in different contexts, such as testing, is trivial.
