Source 
pub fn resolve_client_ip(
    peer_ip: IpAddr,
    xff: Option<&str>,
    trusted: &[IpNet],
) -> IpAddr
Expand description

Resolve the real client IP from X-Forwarded-For if the peer is a trusted proxy.

Walks the X-Forwarded-For chain from right to left, stopping at the first IP that is NOT in a trusted subnet. This is the standard secure algorithm (rightmost non-trusted).
