Struct Config

pub struct Config {
    pub collection: HashMap<String, Value>,
}

The object that keeps the data collection.

This is the yaml file to be used in the following tests:

## tests/settings.yaml

user:
  name: John
  is_real: false
  age: 39
  height: 1.78
  children:
    - Huey
    - Dewey
    - Louie

Fields

collection: HashMap<String, Value>

Implementations

impl Config

pub fn new(source: &str) -> Config

Creates and return the Config instance given the data source path (can be a file or a folder).

Examples:

use kalgan_config::Config;

let config: Config = Config::new("tests/settings.yaml");

pub fn get(&self, key: &str) -> Result<Value, String>

Returns the serde_yaml::Value for the given parameter.

Examples:

assert_eq!(config.get("user.name").unwrap(), "John");

pub fn get_string(&self, key: &str) -> Result<String, String>

Returns the value as a String for the given parameter.

Examples:

assert_eq!(config.get_string("user.name").unwrap(), "John".to_string());

pub fn get_bool(&self, key: &str) -> Result<bool, String>

Returns the value as a bool for the given parameter.

Examples:

assert_eq!(config.get_bool("user.is_real").unwrap(), false);

pub fn get_number(&self, key: &str) -> Result<i64, String>

Returns the value as a i64 for the given parameter.

Examples:

assert_eq!(config.get_number("user.age").unwrap(), 39);

pub fn get_float(&self, key: &str) -> Result<f64, String>

Returns the value as a f64 for the given parameter.

Examples:

assert_eq!(config.get_float("user.height").unwrap(), 1.78);

pub fn get_vec(&self, key: &str) -> Result<Vec<Value>, String>

Returns the value as a Vec<serde_yaml::Value> for the given parameter.

Examples:

assert_eq!(config.get_vec("user.children").unwrap(), vec!["Huey", "Dewey", "Louie"]);

pub fn exists(&self, key: &str) -> bool
