enve

toml [dependencies] enve = "0.2"

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

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

Documentation

Look at the [examples] to see the power!

Usage

```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(())

} ```
