# from-str-sequential

A utility crate which implement a simple `FromStrSequential` trait similar to `FromStr`. Used on enums with unit and un-named variants, and try to convert the string to each variant sequentially (from top to bottom variant). For unit variant,
the string must be the variant name (case-insentive). For un-named variants, the string must match the `FromStr` implementation of the un-named type.

This crate was initially released to allow multiple input formats for `clap::Command`

## Example

```rust
use from_str_sequential::FromStrSequential;

#[derive(Debug, FromStrSequential, PartialEq, Eq)]
enum Foo {
	Bar,
	Baz(usize),
}

assert_eq!(Foo::Bar, Foo::from_str_sequential("bar").unwrap());
assert_eq!(Foo::Bar, Foo::from_str_sequential("BaR").unwrap());
assert_eq!(Foo::Baz(100), Foo::from_str_sequential("100").unwrap());
```
