|
||||
## Features
|
||||
|
||||
- **Derive Configuration:** Easily load configuration from files into your Rust structs.
|
||||
- **Default Values:** Specify default values for struct fields using the `#[from_file(default = "...")]` attribute.
|
||||
- **Default Values:** Specify default values for struct fields using the `#[default = "..."]` attribute.
|
||||
- **Optional Merging:** When the `merge` feature is enabled, allows merging multiple configuration sources.
