Trait Validate 

pub trait Validate {
    // Required method
    fn validate(&self) -> Result<(), Box<ValidationErrors>>;
}

Trait for types that can be validated.

Types implementing this trait can have their values checked against defined constraints, returning validation errors if any constraints are violated.

Deriving

Use the #[derive(Validate)] macro from fastapi_macros to automatically implement this trait based on field attributes.

Example

use fastapi_macros::Validate;
use fastapi_core::validation::Validate;

#[derive(Validate)]
struct CreateUser {
    #[validate(email)]
    email: String,
    #[validate(length(min = 3, max = 50))]
    username: String,
}

let user = CreateUser {
    email: "test@example.com".to_string(),
    username: "testuser".to_string(),
};

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

Required Methods

fn validate(&self) -> Result<(), Box<ValidationErrors>>

Validate this value against all defined constraints.

Errors

Returns ValidationErrors if any constraints are violated.
