Struct ComponentDefinition

pub struct ComponentDefinition {
    pub type_id: fn() -> TypeId,
    pub type_name: &'static str,
    pub scope: fn() -> ComponentScope,
    pub dependencies: fn() -> Vec<TypeId>,
    pub creator: fn(HashMap<TypeId, Arc<dyn Any + Send + Sync>>) -> Result<Arc<dyn Any + Send + Sync>, ComponentError>,
}

Definition structure for registering components with the container

ComponentDefinition contains all the metadata and factory functions needed to create and manage component instances. This structure is typically generated by the #[derive(Component)] macro but can also be created manually.

Examples

use verdure_ioc::{ComponentDefinition, ComponentScope, ComponentInstance};
use std::collections::HashMap;
use std::sync::Arc;
use std::any::TypeId;

#[derive(Debug)]
struct MyService {
    value: i32,
}

let definition = ComponentDefinition {
    type_id: || TypeId::of::<MyService>(),
    type_name: "MyService",
    scope: || ComponentScope::Singleton,
    dependencies: || vec![],
    creator: |_deps| Ok(Arc::new(MyService { value: 42 })),
};

Fields

type_id: fn() -> TypeId

Function that returns the TypeId of the component

type_name: &'static str

Human-readable name of the component type

scope: fn() -> ComponentScope

Function that returns the component’s scope

dependencies: fn() -> Vec<TypeId>

Function that returns the TypeIds of the component’s dependencies

creator: fn(HashMap<TypeId, Arc<dyn Any + Send + Sync>>) -> Result<Arc<dyn Any + Send + Sync>, ComponentError>

Function that creates an instance of the component given its dependencies
