Defined in:

lib/castkit/validators/base.rb

Overview

This class is abstract.

Subclasses must implement ‘#call`.

Abstract base class for all attribute validators.

Validators are responsible for enforcing value constraints (e.g., type checks, format rules, numerical bounds). All validators must inherit from this base class and implement the ‘#call` instance method.

Supports both instance-level and class-level invocation via ‘.call`.

Direct Known Subclasses

CollectionValidator, NumericValidator, StringValidator

Class Method Summary

• .call(value, options:, context:) ⇒ void

  Entry point for validating a value using the validator class.

Instance Method Summary

• #call(value, options:, context:) ⇒ void abstract

  Validates the value.

Class Method Details

.call(value, options:, context:) ⇒ void

This method returns an undefined value.

Entry point for validating a value using the validator class.

Instantiates the validator and invokes ‘#call` with the provided arguments.

Parameters:

• value (Object) —

  the value to validate

• options (Hash) —

  additional validation options (e.g., ‘min`, `max`, `format`)

• context (Symbol, String, Hash) —

  context for the validation (usually the attribute name)

Raises:

• (Castkit::AttributeError) —

  if validation fails and ‘raise_type_errors` is true

def call(value, options:, context:)
  new.call(value, options: options, context: context)
end

Instance Method Details

#call(value, options:, context:) ⇒ void

This method is abstract.

This method returns an undefined value.

Validates the value.

Parameters:

• value (Object) —

  the value to validate

• options (Hash) —

  validation options (e.g., min, max, format)

• context (Symbol, String, Hash) —

  context for validation errors

Raises:

• (NotImplementedError) —

  if not implemented in subclass

def call(value, options:, context:)
  raise NotImplementedError, "#{self.class.name} must implement `#call`"
