This crate provides derive macro Display and FromStr.
These macros use common helper attributes to specify the format.
Add this to your Cargo.toml:
[dependencies]
parse-display = "0.10.0"See #[derive(Display)] documentation for details.
use parse_display::{Display, FromStr};
#[derive(Display, FromStr, PartialEq, Debug)]
#[display("{a}-{b}")]
struct X {
a: u32,
b: u32,
}
assert_eq!(X { a:10, b:20 }.to_string(), "10-20");
assert_eq!("10-20".parse(), Ok(X { a:10, b:20 }));
#[derive(Display, FromStr, PartialEq, Debug)]
#[display(style = "snake_case")]
enum Y {
VarA,
VarB,
}
assert_eq!(Y::VarA.to_string(), "var_a");
assert_eq!("var_a".parse(), Ok(Y::VarA));This project is dual licensed under Apache-2.0/MIT. See the two LICENSE-* files for details.
