Extracting an Enum Environment Variable

std::env::set_var("foo", "bar");

#[derive(Debug, Default, Clone)]
enum Foo {
    #[default]
    Bar,
    Baz,
}

let foo = EnumVariableBuilder::default()
    .name("foo".to_string())
    .add_option("bar".to_string(), Foo::Bar)
    .add_option("baz".to_string(), Foo::Baz)
    .build()
    .unwrap();

assert!(matches!(foo, Foo::Bar));

Extracting Any Environment Variable

use env_extract::AnyVariableBuilder;

std::env::set_var("foo", "bar");

let foo = AnyVariableBuilder::default()
   .name("foo".to_string())
   .build()
   .unwrap();

assert_eq!(foo, "bar");
