pub fn add( &mut self, attribute: impl Into<String>, validator: impl Validator + 'static, )

Adds a validator for the given attribute.

pub fn validators_on(&self, attribute: &str) -> Vec<&dyn Validator>

Returns validators registered for the given attribute in registration order.

pub fn validate( &self, attrs: &dyn Fn(&str) -> Option<Value>, errors: &mut Errors, ) -> Result<(), String>

Runs all validations and appends any produced errors.

pub fn validate_with_context( &self, attrs: &dyn Fn(&str) -> Option<Value>, errors: &mut Errors, context: &ValidationContext, ) -> Result<(), String>
