salak

Salak is a multi layered configuration loader and zero-boilerplate configuration parser, with many predefined sources.

Please refer to salak doc.

Notice

Please notice that salak-0.9.* is totally rewrited, so the APIs may changes much, and some functions may be removed. They will be added in later version.

Quick Example

use salak::*;

#[derive(Debug, FromEnvironment)]
#[salak(prefix = "config")]
struct Config {
    #[salak(default = false)]
    verbose: bool,
    optional: Option<String>,
    #[salak(name = "val")]
    value: i64,
}
let env = Salak::builder()
    .set("config.val", "2021")
    .build()
    .unwrap();
let config = env.get::<Config>().unwrap();
assert_eq!(2021, config.value);
assert_eq!(None, config.optional);
assert_eq!(false, config.verbose);

Trait FromEnvironment

Salak Factory

salak_factory can initialize resource based on salak, such as redis, postgresql, etc.

use salak::*;
use salak_factory::{redis_default::RedisConfig, Factory};

fn main() -> Result<(), PropertyError> {
    let env = Salak::new()?;
    let redis_pool = env.build::<RedisConfig>()?;
    let redis_conn = redis_pool.get()?;
    let _: u64 = redis_conn.set("hello", 1u64)?;
    Ok(())
}
