macos-routing-table
A basic parser and route testing API for macOS devices. Parses a static or live routing table (via the netstat
command) and provides an interface to inspect tht table, and to determine which gateway and interface would be used to route traffic to a given address.
Analyzes both the IPv4 and IPv6 routing tables. Minimal support for zones (parsing only at this time).
Example - find the gateway for an address
use anyhow::Result;
use macos_routing_table::{RouteEntry, RoutingTable};
#[tokio::main]
async fn main() -> Result<()> {
let rt = RoutingTable::load_from_netstat().await?;
let addr = "1.1.1.1".parse()?;
if let Some(RouteEntry {
net_if, gateway, ..
}) = rt.find_route_entry(addr)
{
println!("{addr:?} => {gateway} via {net_if}");
} else {
println!("No route to {addr:?}");
}
Ok(())
}
