Function authenticate_request 

pub async fn authenticate_request(
    req: &mut ServiceRequest,
    data: &MiddlewareData,
) -> Result<(), SignatureError>

authenticate_request is a function that verifies the signature of an incoming request. Intended to allow for manual handling of authentication, or for use with other middleware.

Arguments

• req - mutable reference to the incoming request
• data - reference to the MiddlewareData struct

Note: This function does not add the AuthenticationInfo struct to the request extensions. Additionally, this function does not reject requests if the signature is invalid. Instead, it returns a Result with an Error if the signature is invalid.
