## Usage

```rust

let dep = "requests[security, socks] <= 2.28.1, == 2.28.*; python_version > '3.7' and extra == 'http'";

let parsed = parse(dep).unwrap();

let expected = Dependency {

    name: "requests",

    extras: vec!["security", "socks"],

    spec: Some(Spec::Version(vec![

        VersionSpec {

            comparator: Comparator::Le,

            version: "2.28.1",

        },

        VersionSpec {

            comparator: Comparator::Eq,

            version: "2.28.*",

        },

    ])),

    marker: Some(Marker::And(

        Box::new(Marker::Operator(

            Variable::PythonVersion,

            Operator::Comparator(Comparator::Gt),

            Variable::String("3.7"),

        )),

        Box::new(Marker::Operator(

            Variable::Extra,

            Operator::Comparator(Comparator::Eq),

            Variable::String("http"),

        )),

    )),

};

assert_eq!(parsed, expected);

```
