Trait Validate 

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

    // Provided method
    fn validate_with_context(
        &self,
        _ctx: &dyn Any,
    ) -> Result<(), ValidationErrors> { ... }
}

The core validation trait for Rusdantic.

This trait is automatically implemented by #[derive(Rusdantic)]. It validates all fields of a struct according to their declared rules and returns all validation errors at once (collect-all, not fail-fast).

Example

use rusdantic::{Rusdantic, Validate};

#[derive(Rusdantic)]
struct User {
    #[rusdantic(email)]
    email: String,
}

let user = User { email: "not-an-email".to_string() };
assert!(user.validate().is_err());

Required Methods

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

Validate this value, collecting all validation errors.

Returns Ok(()) if all validation rules pass, or Err(ValidationErrors) containing all validation failures with their field paths.

Provided Methods

fn validate_with_context(&self, _ctx: &dyn Any) -> Result<(), ValidationErrors>

Validate with external context (database connection, config, etc.).

This method enables validators that need access to external resources. The default implementation ignores the context and delegates to validate().

Example

struct DbContext { /* ... */ }

let user = User { email: "user@example.com".to_string() };
let ctx = DbContext { /* ... */ };
user.validate_with_context(&ctx)?;
