EString

toml [dependencies] estring = "0.3"

A simple way to parse a string using type annotations.

This package was originally designed for [enve].

Documentation

For more details, see [examples].

Basic

```rust use estring::EString;

fn main() -> estring::Result<()> { let res: i32 = EString::from("10").parse()?; assert_eq!(res, 10); Ok(()) } ```

You can use predefined structs like SepVec if you enable the structs feature.

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

```rust use estring::{SepVec, EString};

type PlusVec = SepVec; type MulVec = SepVec;

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

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

} ```

You can also use predefined aggregators if you enable the aggs feature.

```rust use estring::{Aggregate, EString, Product, SepVec, Sum};

type PlusVec = SepVec; type MulVec = SepVec;

fn main() -> estring::Result<()> { let res = EString::from("10+5*2+3") .parse::>>>>()? .agg();

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

} ```
