# Lightweight Inversion Of Control
``` rust
use {minfac::{Registered, ServiceCollection}};
let mut collection = ServiceCollection::new();
collection
.with::<Registered<u8>>()
.register(|byte| byte as i16 * 2);
assert_eq!(Some(2i16), provider.get::<i16>());
```
# Features
- Register Types/Traits which are not part of your crate (e.g. std::*). No macros needed.
- Service registration from separately compiled dynamic libraries. see `examples/distributed_simple` for more details
- Transient services are retrieved as `T` without any additional frills, SharedServices as `Arc<T>`
- Inheritance instead of scoped services (Service requests can be delegated to parent `ServiceProvider`s)
- Service discovery, (`provider.get_all::<MyService>()` returns an iterator, which lazily generates all registered `MyService` instances)
- Fail fast. When building a `ServiceProvider` all registered services are checked to
- have all dependencies
- contain no dependency-cycles
- Common pitfalls of traditional IOC are prevented by design
- Singleton services cannot reference scoped services, as scoped services don't exist
- Shared services cannot outlive their `ServiceProvider` (checked at runtime when debug_assertions are enabled)
- `ServiceProvider` implements Send+Sync and is threadsafe without using locks

## Required Tasks for stable release
✅ Transient services - New instance per request
✅ Shared services - Shared instance per ServiceProvider
✅ Instance services - Shared instance per ServiceProviderFactory
✅ ServiceProviderFactory for creating ServiceProvider's with minimal overhead
✅ ServiceProviderFactory inherit services from ServiceProvider
⬜ ServiceProviderFactory inherit services from other ServiceProviderFactory
✅ Replaceable strategy for service identification (TypeIds might change between rust versions)
✅ Recursive dependencies check
✅ Missing dependencies check
⬜ Make all structs FFI-Safe
⬜ Remove global Error handler. Use transition from ServiceCollection to ServiceProvider to replace default Error-Hander
