Sanitizing forms in vibe.d. How?

[aberba via Digitalmars-d-learn]

In php, I use built-in functions like 
filter_var(FILTER_VALIDATE_EMAIL, $email). There are other 
constants for different data types.

Again, there is mysqli_real_escape_string() for escaping SQL 
injection/harmful characters.


What are my options in vibe.d or even D?
