# parse-display
[](https://crates.io/crates/parse-display)
[](https://docs.rs/parse-display/)
[](https://github.com/frozenlib/parse-display/actions)
This crate provides derive macro `Display` and `FromStr`.
These macros use common helper attributes to specify the format.
## Install
Add this to your Cargo.toml:
```toml
[dependencies]
parse-display = "0.10.0"
```
## Documentation
See [`#[derive(Display)]`](https://docs.rs/parse-display/latest/parse_display/derive.Display.html) documentation for details.
## Example
```rust
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));
```
