Updated documentation to reflect inet allows for IpAddr
//! | Rust type | Postgres type(s) |
//! |---------------------------------------|------------------------------------------------------|
//! | `ipnetwork::IpNetwork` | INET, CIDR |
+//! | `std::net::IpAddr` | INET, CIDR |
+//!
+//! Note that because `IpAddr` does not support network prefixes, it is an error to attempt to decode
+//! an `IpAddr` from a `INET` or `CIDR` value with a network prefix smaller than the address' full width:
+//! `/32` for IPv4 addresses and `/128` for IPv6 addresses.
+//!
+//! `IpNetwork` does not have this limitation.
