enve
[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.

Usage
use enve::SepVec;
type MinusVec<T> = SepVec<T, '-'>;
type PlusVec<T> = SepVec<T, '+'>;
type MulVec<T> = SepVec<T, '*'>;
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(())
}
