Trait ValidationCheck

pub trait ValidationCheck: Sized {

Expand description

A trait for performing validation checks and handling validation-related errors.

This trait provides methods to:

Create a new validation error instance from an error store.
Collect and validate errors, returning a result depending on whether any errors are found.

§Associated Types

Self: The concrete type that implements the ValidationCheck trait, which represents validation errors.

§Required Methods

§`validate_new`

Creates a new instance of the implementing type using a provided ValidateErrorStore.

§Parameters

messages: An instance of ValidateErrorStore that holds validation error information.

§Returns

Self: A new instance of the implementing type initialized with the given error messages.

§Provided Methods

§`validate_check`

Performs a validation check using a ValidateErrorCollector. If the collector contains errors, it returns an error wrapped in the implementing type; otherwise, it succeeds with Ok(()).

§Parameters

messages: An instance of ValidateErrorCollector that holds collected validation errors.

§Returns

Ok(()): If the collector does not contain any errors.
Err(Self): If the collector contains errors, an error instance of the implementing type is returned.

The default implementation checks if the provided messages is empty. If it is empty, it returns an Ok(()). Otherwise, it converts the messages into a ValidateErrorStore and creates a new validation error instance using validate_new.
