Overview

Validator for boolean attributes.

Accepts various representations of boolean values, including strings and integers. Converts common truthy/falsy string values into booleans, otherwise raises a type error.

This validator is typically used internally by ‘Castkit::Types::Boolean`.

Examples:

validator = Castkit::Validators::BooleanValidator.new
validator.call("true", _options: {}, context: :enabled) # => true
validator.call("0", _options: {}, context: :enabled)    # => false
validator.call("nope", _options: {}, context: :enabled) # raises Castkit::AttributeError
