### Define and Inject Service Configuration Block

Source: https://github.com/soapun/concoction/blob/main/README.md

Define a Pydantic model for the 'app.service' configuration block and load it from a YAML file. This method injects the entire 'service' configuration block.

```python
import yaml  # pip install pyyaml
from pydantic import BaseModel
from concoction import Configuration, set_global_config


# define config with injection

@Configuration("app.service")
class ServiceConfig(BaseModel):
    host: str
    port: int


# Load configuration from a YAML file
with open("config.yaml") as f:
    config = yaml.safe_load(f)

set_global_config(config)

# Create an instance of the configuration model
app_config = ServiceConfig()
```

### Inject Individual Service Configuration Fields

Source: https://github.com/soapun/concoction/blob/main/README.md

Define a Pydantic model to inject individual fields ('host' and 'port') from the 'app.service' configuration path using the Value class. This provides granular control over configuration injection.

```python
from concoction.values.pydantic import Value


class ServiceConfig(BaseModel):
    host: str = Value("app.service.host")
    port: int = Value("app.service.port")
```
