Crate serde_env

serde-env will allow deserializing env into structs.

The biggest different between envy is serde-env supports deserialize _ seperated env into nests structs. That means we will treat env as _ seperated tree instead of a flat map.

For examples:

use serde::Deserialize;
use serde_env::from_env;

#[derive(Debug, Deserialize)]
struct Cargo {
    home: String,
}

#[derive(Debug, Deserialize)]
struct Test {
    #[cfg(windows)]
    #[serde(rename="userprofile")]
    home: String,
    #[cfg(not(windows))]
    home: String,
    cargo: Cargo,
}

let t: Test = from_env().expect("deserialize from env");

assert!(!t.home.is_empty());
assert!(!t.cargo.home.is_empty());
println!("{:?}", t)
