Struct promkit::validate::ValidatorManager

pub struct ValidatorManager<T: ?Sized> { /* private fields */ }

A generic structure for validating inputs of any type.

This structure allows for the definition of custom validation logic and error message generation for inputs of a specified type. It encapsulates a validator function and an error message generator function, both of which operate on references to the input.

Implementations

impl<T: ?Sized> ValidatorManager<T>

pub fn new( validator: Validator<T>, error_message_generator: ErrorMessageGenerator<T> ) -> Self

Constructs a new Validator instance with the specified validator and error message generator functions.

Arguments

• validator - A function that takes a reference to an input of type T and returns a boolean indicating whether the input passes the validation.
• error_message_generator - A function that takes a reference to an input of type T and returns a String that describes the validation error.

Returns

Returns a new instance of Validator<T>.

pub fn validate(&self, input: &T) -> bool

Validates the given input using the encapsulated validator function.

Arguments

• input - A reference to the input of type T to be validated.

Returns

Returns true if the input passes the validation, otherwise false.

pub fn generate_error_message(&self, input: &T) -> String

Generates an error message for the given input using the encapsulated error message generator function.

Arguments

• input - A reference to the input of type T for which to generate an error message.

Returns

Returns a String that describes the validation error.
