Server validation

As explained in Rust Servers, Services, and Apps

Server-side validation is validation of request data performed by a server before the requested operation is completed.

Server validation checks request data on the server before completing the requested operation. In tutor registration, it complements browser checks rather than replacing them. section 8.2

A registration request follows this flow:

  • Render the registration form from the GET / route. section 8.2
  • Submit the form with a POST request to /register, where the server handles the request before registration proceeds. section 8.2

Tutor registration

A username field may require 6–12 characters, while password and other fields are mandatory in the HTML form. These browser checks provide early feedback; the submitted request still reaches the server for validation. section 8.2

How Rust Servers, Services, and Apps covers it

How deep it goes
Contrasts browser constraints with server handling but does not detail validation rules or implementation code.
Examples
Uses a tutor registration form with required fields, username length limits, and a POST /register submission.
What it assumes
Assumes familiarity with HTML forms and HTTP routes while introducing their roles in a server-backed registration workflow.
What you can do after
Evaluate how browser checks and server handling divide responsibilities in a registration request flow.
How it connects
Connects client-side validation, HTML forms, HTTP POST requests, backend services, and data persistence.
