Function validate_request 

Source 
pub fn validate_request(req: &SystemRequest) -> ValidationResult<()>
Expand description

Validate a request. Pure — does no I/O.

Rules derived from the spec:

  • at least one question
  • all question kinds validate their own criteria shape
  • for Choice: criteria must be non-empty (no explicit lower bound in spec but a zero-option question is meaningless and would 422 from the real API)
