Attribute Macro StringEnum

Source 
#[StringEnum]
Expand description

This procedural macro generates JS ‘string-like’ enums, which support from and to string conversions on all members.

use map_enum::*;
use std::str::FromStr;

#[derive(Debug)]
#[StringEnum]
pub enum Method {
    Get = "Hi",
    Post,
}

assert_eq!(Method::Get.to_string(), "Hi".to_string());
assert_eq!(Method::Post.to_string(), "Post".to_string());
assert_eq!(Method::from_str("Hi").unwrap(), Method::Get);
assert_eq!(Method::from_str("Post").unwrap(), Method::Post);
assert!(Method::from_str("other").is_err());
