Trait ConfigLoader 

pub trait ConfigLoader<T> {
    // Required method
    fn load_layered(
        config_file: Option<PathBuf>,
        env_prefix: &str,
        defaults: T,
    ) -> Result<T, ConfigError>
       where T: DeserializeOwned + Default;
}

Base trait for configuration loading with layered approach

Required Methods

fn load_layered( config_file: Option<PathBuf>, env_prefix: &str, defaults: T, ) -> Result<T, ConfigError>

where T: DeserializeOwned + Default,

Load configuration from multiple sources in order of precedence:

1. Command line arguments (highest priority)
2. Environment variables
3. Configuration file
4. Default values (lowest priority)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
