A simple way to parse a string using type annotations.

This package was originally designed for enve.

Documentation

For more details, see examples.

Usage

use estring::{SepVec, EString};

type PlusVec<T> = SepVec<T, '+'>;
type MulVec<T> = SepVec<T, '*'>;

fn main() -> estring::Result<()> {
    let res = EString::from("10+5*2+3")
        .parse::<PlusVec<MulVec<f32>>>()?
        .iter()
        .map(|m| m.iter().product::<f32>())
        .sum::<f32>();

    assert_eq!(res, 23.0);
    Ok(())
}

You can use custom types as annotations! Just implement estring::ParseFragment!
