Trait Validate

pub trait Validate {
    // Required method
    fn validate(&self) -> Vec<ValidationError>;
}

A trait for validating structs.

Implement this trait for your structs to define custom validation logic. The validate method should return a vector of ValidationErrors indicating any validation failures.

Required Methods

fn validate(&self) -> Vec<ValidationError>

Validates the current instance and returns a list of validation errors.

If the instance is valid, the returned vector should be empty.

Examples

use struct_validation_core::{Validate, ValidationError};

struct User {
    username: String,
    email: String,
}

impl Validate for User {
    fn validate(&self) -> Vec<ValidationError> {
        let mut errors = Vec::new();
         
        if self.username.is_empty() {
            errors.push(ValidationError::new("username", "must not be empty"));
        }
         
        if !self.email.contains('@') {
            errors.push(ValidationError::new("email", "must contain '@'"));
        }
         
        errors
    }
}
