rust tiny-ping

Ping function implemented in rust, made for small compile times.

Small async ICMP library. No proc macros.

Usage

use std::{net::IpAddr, time::Duration};

use tiny_ping::Pinger;

# async fn example() -> Result<(), Box<dyn std::error::Error>> {
let mut pinger = Pinger::new("1.1.1.1".parse::<IpAddr>()?)?;
pinger.timeout(Duration::from_secs(1));

let result = pinger.ping(1).await?;
println!("reply from {} in {:?}", result.reply.source, result.rtt);
# Ok(())
# }

Use PingRequest when you need to control the ICMP echo payload:

use std::{net::IpAddr, time::Duration};

use tiny_ping::{Pinger, PingRequest};

# async fn example() -> Result<(), Box<dyn std::error::Error>> {
let mut pinger = Pinger::new("1.1.1.1".parse::<IpAddr>()?)?;
pinger.timeout(Duration::from_secs(1));

let request = PingRequest::new(1).payload(b"tiny-ping");
let result = pinger.ping(request).await?;
println!("reply payload was {} bytes", result.reply.payload_len);
# Ok(())
# }

For multicast or other cases where more than one host may reply to a single request, use ping_replies:

use std::{net::{Ipv6Addr, SocketAddr, SocketAddrV6}, time::Duration};

use tiny_ping::{Pinger, SocketType};

# async fn example() -> Result<(), Box<dyn std::error::Error>> {
let target = SocketAddr::V6(SocketAddrV6::new(
    "ff02::1".parse::<Ipv6Addr>()?,
    0,
    0,
    2,
));
let mut pinger = Pinger::with_socket_addr(target, SocketType::Raw)?;
pinger.timeout(Duration::from_secs(1));

for result in pinger.ping_replies(1).await? {
    println!("reply from {} in {:?}", result.reply.source, result.rtt);
}
# Ok(())
# }

Raw sockets usually need root or capabilities.

DGRAM sockets can work without that on some systems:

use std::net::IpAddr;

use tiny_ping::{Pinger, SocketType};

# async fn example() -> Result<(), Box<dyn std::error::Error>> {
let pinger = Pinger::with_socket_type(
    "1.1.1.1".parse::<IpAddr>()?,
    SocketType::Dgram,
)?;

let result = pinger.ping(1).await?;
println!("reply from {} in {:?}", result.reply.source, result.rtt);
# Ok(())
# }

For repeated pings, use PingSeries:

use std::{net::IpAddr, time::Duration};

use tiny_ping::{Pinger, PingSeries};

# async fn example() -> Result<(), Box<dyn std::error::Error>> {
let mut pinger = Pinger::new("1.1.1.1".parse::<IpAddr>()?)?;
pinger.timeout(Duration::from_secs(1));

let series = PingSeries::new(1, 4).interval(Duration::from_secs(1));
let results = pinger.ping_many(series).await;
println!(
    "{} transmitted, {} received, {:.1}% loss",
    results.summary.transmitted,
    results.summary.received,
    results.summary.loss,
);
# Ok(())
# }

Use bind_source to bind the socket to a local source address. The port is ignored for ICMP.

Tests
