Validatron

Validatron is a data structure validation library for Rust that is designed for performing extensive integrity checks on user supplied data prior to use.

It is heavily inspired by the keats/validator crate but with different design choices:

• do not fail fast, return as many errors as possible
• return a serializable error type
• provide easily extendable validators

Example

(Check the examples directory for additional examples.)

use validatron::Validate;

#[derive(Debug, Validate)]
struct MyStruct {
    #[validatron(min = 42)]
    a: i64,
    #[validatron(max_len = 5)]
    b: Vec<u32>,
}

fn main() {
    let good = MyStruct {
        a: 666,
        b: vec![],
    };

    assert!(good.validate().is_ok());

    let bad = MyStruct {
        a: 1,
        b: vec![42; 25],
    };

    let result = bad.validate();
    assert!(result.is_err());

    println!("{:#?}", result);
}
