Trait ConcreteComponent 

pub trait ConcreteComponent: Sized + ErasedComponent {
    type Config: Any + 'static;
    type Error: Error + Send + Sync + 'static;

    const TYPE_NAME: &'static str;
    const PACKAGE: ComponentPackage = ComponentPackage::Application;
    const DEPENDENCIES: &'static [DependencyDecl] = _;

    // Required methods
    fn new(config: &Self::Config) -> Result<Self, Self::Error>;
    fn serialize(&self) -> Vec<u8> ;
    fn restore(bytes: &[u8]) -> Result<Self, RestoreError>;
}

Polymorphism contract. Implementing this trait IS the registration mechanism — no global registry, no macro required. Serialized state must be self-contained so restore reconstructs without the original Config.

Required Associated Constants

const TYPE_NAME: &'static str

Stable identifier. Convention: <crate>::<TypeName>.

Provided Associated Constants

const PACKAGE: ComponentPackage = ComponentPackage::Application

Origin tag; defaults to Application.

const DEPENDENCIES: &'static [DependencyDecl] = _

Sibling components this depends on. Populated by the bb::Concrete derive from #[bb::depends(...)].

Required Associated Types

type Config: Any + 'static

Per-deployment config. Use () for stateless concretes.

type Error: Error + Send + Sync + 'static

Error from Self::new; use Infallible if construction can’t fail.

Required Methods

fn new(config: &Self::Config) -> Result<Self, Self::Error>

Construct from &Self::Config. Install calls this once per slot.

fn serialize(&self) -> Vec<u8>

Serialize state to bytes, including config-derived fields.

fn restore(bytes: &[u8]) -> Result<Self, RestoreError>

Reconstruct from serialize output.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
