Struct IpPrefix 

pub struct IpPrefix { /* private fields */ }

An IP address with a CIDR prefix length.

Equivalent to Go’s netip.Prefix — an IpAddr plus a prefix length in bits (0–32 for v4, 0–128 for v6).

let p = IpPrefix::new(Ipv4Addr::new(10, 0, 0, 1).into(), 24);
assert!(p.contains(Ipv4Addr::new(10, 0, 0, 99).into()));
assert!(!p.contains(Ipv4Addr::new(10, 0, 1, 1).into()));

Implementations

impl IpPrefix

pub fn new(addr: IpAddr, bits: u8) -> IpPrefix

Construct a prefix. bits is clamped silently to the protocol max: at most 32 for v4 and 128 for v6.

pub fn addr(self) -> IpAddr

The address part. May or may not have the host bits zeroed; this matches Go’s semantics so that 10.0.0.5/24 round-trips with the host bits.

pub fn bits(self) -> u8

The prefix length in bits.

pub fn contains(self, other: IpAddr) -> bool

True if other falls within this prefix (host bits ignored).

pub fn masked(self) -> IpPrefix

Return a prefix with host bits zeroed (the canonical network address).

pub fn is_v4(self) -> bool

Is this an IPv4 prefix?

pub fn is_v6(self) -> bool

Is this an IPv6 prefix?

pub fn is_valid(self) -> bool

True if this prefix has zero bits set on the address (an empty/unspecified).
