Function load 

pub fn load<T: DeserializeOwned>(config_dir: &str) -> Result<T>

Loads and deserializes a YAML config file for the current environment.

The file is resolved as {config_dir}/{APP_ENV}.yaml. After reading, all ${VAR} and ${VAR:default} placeholders are replaced with values from the process environment before deserialization.

Errors

Returns an error when:

• The config file cannot be read.
• A required ${VAR} placeholder references an unset environment variable.
• The YAML cannot be deserialized into T.

Example

use modo::config::load;
use modo::Config;

let config: Config = load("config/").unwrap();
