Enum Resolution 

#[non_exhaustive]
pub enum Resolution {
    Peer(IpAddr),
    Forwarded(IpAddr),
    Invalid(InvalidForwarding),
    Unavailable,
}

How the client address was resolved, or why it was not.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Peer(IpAddr)

The connection’s peer is the client: it is not a trusted proxy, or it is one that forwarded no address where none is required.

Forwarded(IpAddr)

A trusted proxy forwarded the address: the first one outside the trusted proxies, read right to left, or the leftmost when every hop is trusted.

Invalid(InvalidForwarding)

A trusted proxy forwarded something that cannot be read where the client’s address should be. No address resolves: the peer is a proxy, not the client.

Unavailable

The server recorded no connection information, so there is no peer to start from, or a trusted proxy reported nothing where an address is required.
