Which statement best describes the validation pipe and class-validator in NestJS?

The class-validator and validation pipes are unrelated features in NestJS, serving different purposes in isolation.

The class-validator is a library used for defining database schemas in TypeORM, while the validation pipes are used for input validation in NestJS.

The class-validator defines validation rules for entities and DTOs in NestJS, ensuring data integrity and validity. At the same time, validation pipes provide a global mechanism for validating input data at various stages of request processing.

The class-validator is only used for creating custom pipes in NestJS, while the validation pipes are used for persisting data into the database.
