Function openssl_verify::verify_callback

pub fn verify_callback(domain: &str, preverify_ok: bool, x509_ctx: &X509StoreContext) -> bool

A convenience wrapper around verify_hostname that implements the logic for OpenSSL's certificate verification callback.

If preverify_ok is false or the certificate depth is not 0, it will simply return the value of preverify_ok. It will otherwise validate the that the provided fully qualified domain name matches that of the leaf certificate.
