Core Concepts

Container

The Container is the central piece of dependency-injector. It stores and manages your services. Any type that implements Send + Sync + 'static can be registered.

Service Lifetimes

Dependency Injector supports three service lifetimes:

Singleton

One instance shared everywhere. Created immediately on registration.

Lazy Singleton

One instance shared everywhere. Created on first access.

Transient

New instance created every time you resolve the service.
