Struct Ipv4Route 

pub struct Ipv4Route {
    pub interface: Option<String>,
    pub source: Option<Ipv4Addr>,
    pub gateway: Option<Ipv4Addr>,
    pub is_local: bool,
    pub prefix_len: u8,
    pub metric: u32,
}

Routing information for an IPv4 destination.

Fields

interface: Option<String>

The outgoing interface name.

source: Option<Ipv4Addr>

The source IP address to use.

gateway: Option<Ipv4Addr>

The next-hop gateway IP (if not on local network).

is_local: bool

Whether the destination is on the local network.

prefix_len: u8

The network mask (prefix length).

metric: u32

Route metric (lower is better).

Implementations

pub fn none() -> Self

Create an empty route (no routing info available).

pub fn local(interface: String, source: Ipv4Addr) -> Self

pub fn via_gateway( interface: String, source: Ipv4Addr, gateway: Ipv4Addr, ) -> Self

Create a route via a gateway.

pub fn is_valid(&self) -> bool

Check if this route is valid (has interface).

pub fn next_hop(&self, dst: Ipv4Addr) -> Ipv4Addr

Get the next-hop address (gateway or destination if local).
