enve

enve helps you work with environment variables and convert it to any type using only type annotations.

Look at the examples to see the power!

All standard environment variable types are included, but enve under the hood uses estring, so you can easily create your own type.

Getting started

```rust use enve::SepVec;

type MinusVec = SepVec; type PlusVec = SepVec; type MulVec = SepVec;

fn main() -> Result<(), enve::Error> { enve::sset("E", "10+5*2-3");

let res: f32 = enve::get::<PlusVec<MinusVec<MulVec<f32>>>>("E")
    .unwrap()
    .iter()
    .map(|p| {
        p.iter()
            .map(|m| m.iter().product::<f32>())
            .reduce(|acc, v| acc - v)
            .unwrap_or_default()
    })
    .sum::<f32>();

println!("result: {}", res);

Ok(())

} ```
