[REQ][rust-server] Regex pattern validation for strings

[Foorack]

Is your feature request related to a problem? Please describe.

Taking the following object as example:

    UserID:
      type: string
      title: UserID
      pattern: '[0-9a-fA-F]{8}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{12}'

The server then allows invalid user ID's which are not compliant with the defined pattern.

Hm, I tried replicating this issue, and it will indeed accept something like "12345678-1234-1234-1234-123456789012111". However, I think this is actually an issue with your regex rather than the generator not correctly evaluating the regex.

In the previous example, "12345678-1234-1234-1234-123456789012" is a valid substring and therefore, is accepted.

Try adding ^$ tags to the beginning and end so that the entire string has to be that valid substring

What do you mean? Currently in Rust there is not regex checking at all. Your testing is specific to python server implementation, meanwhile in Rust-server this check is completely missing.

This feature request is to track this missing feature in Rust. I am planning to implement it in a future PR, just wanted to open a tracking Issue ticket first.

I can confirm that this doesn't seem to be implemented as of v5.3.1. Would love to see this implemented though.
