# Valitron is a validator on ergonomics

In the future, modularization will be supported

Inspired by axum

- Build-in rule, e.g. Required, StartWith ...
- Closure validate
- Related validate, e.g. password confirm
- Custom rule with other parameter
- Check / modify input data
- Custom error message
- collect validate error messages
- Support all types data on `#[dervic(Serialize, Deserialize)]` ( visit [`serde`](https://serde.rs/) for more info)

## Examples

```rust
fn main() {
    let validator = Validator::new()
        .rule("name", Required.and(StartWith("hello")))
        .rule("age", custom(age_limit))
        .message([
            ("name.required", "name is required"),
            ("name.start_with", "name should be starts with `hello`"),
        ]);

    let person = Person {
        name: "li",
        age: 18,
    };

    let res = validator.validate(person);
}

fn age_limit(n: &mut u8) -> Result<(), &'static str> {
    if *n >= 25 && *n <= 45 {
        return Ok(());
    }
    Err("age should be between 25 and 45")
}
```
