#34 in #string-representation
7KB
This crate provides a macro to create a unitary enum and conversions from enum variants to a string representation and vice versa.
Why another crate?
The string representation does not need to be the same as the enum variant's identifier. See the example below for clarification.
Example
#[macro_use] extern crate enum_str;
use std::str::FromStr;
use enum_str::{Error, AsStr};
fn main() {
enum_str! {
Fruit,
(Apple, "🍎"),
(Pineapple, "🍍"),
(Strawberry, "🍓"),
}
assert_eq!("🍎", Fruit::Apple.as_str());
assert_eq!(Fruit::Apple, Fruit::from_str("🍎").unwrap());
}
