Crate use_ip 

use-ip

use-ip provides small helpers for parsing, normalizing, and classifying IP address literals.

Experimental: this crate is below 0.3.0 and the API may change.

Example Usage

use use_ip::{detect_ip_kind, is_private_ip, normalize_ip, IpKind};

assert_eq!(detect_ip_kind("192.168.1.20"), IpKind::V4);
assert!(is_private_ip("fd00::1"));
assert_eq!(normalize_ip("2001:0db8::0001"), Some("2001:db8::1".to_string()));

Scope

• IP address validation and normalization.
• Basic IP classifications such as loopback, private, link-local, and multicast.

Non-goals

• Geolocation.
• Network interface inspection.
• Packet parsing.

Structs

IpParts

Stores an original IP-like input with its detected kind.

Enums

IpKind

Classifies a parsed IP literal.

Functions

detect_ip_kind

Detects whether the input is IPv4, IPv6, or unknown.

is_ip

Returns true when the input is a valid IPv4 or IPv6 literal.

is_ipv4

Returns true when the input is a valid IPv4 literal.

is_ipv6

Returns true when the input is a valid IPv6 literal.

is_link_local_ip

Returns true when the input is a link-local IPv4 or IPv6 literal.

is_loopback_ip

Returns true when the input is a loopback IP literal.

is_multicast_ip

Returns true when the input is a multicast IP literal.

is_private_ip

Returns true when the input is a private IPv4 or unique-local IPv6 literal.

is_unspecified_ip

Returns true when the input is an unspecified IP literal.

normalize_ip

Normalizes a valid IP literal to Rust’s canonical string form.
