//! Trippy - A network tracing library.
//!
//! This crate provides the core network tracing facility used by the
//! standalone [Trippy](https://trippy.rs) application.
//!
//! Note: the public API is not stable and is highly likely to change
//! in the future.
//!
//! # Example
//!
//! The following example builds and runs a tracer with default configuration
//! and prints out the tracing data for each round:
//!
//! ```no_run
//! # fn main() -> anyhow::Result<()> {
//! # use std::net::IpAddr;
//! # use std::str::FromStr;
//! use trippy_core::Builder;
//!
//! let addr = IpAddr::from_str("1.1.1.1")?;
//! Builder::new(addr)
//!     .build()?
//!     .run_with(|round| println!("{:?}", round))?;
//! # Ok(())
//! # }
//! ```
//!
//! The following example traces using the UDP protocol with the Dublin ECMP
//! strategy with fixed src and dest ports.  It also operates in unprivileged
//! mode (only supported on some platforms):
//!
//! ```no_run
//! # fn main() -> anyhow::Result<()> {
//! # use std::net::IpAddr;
//! # use std::str::FromStr;
//! use trippy_core::{Builder, MultipathStrategy, Port, PortDirection, PrivilegeMode, Protocol};
//!
//! let addr = IpAddr::from_str("1.1.1.1")?;
//! Builder::new(addr)
//!     .privilege_mode(PrivilegeMode::Unprivileged)
//!     .protocol(Protocol::Udp)
//!     .multipath_strategy(MultipathStrategy::Dublin)
//!     .port_direction(PortDirection::FixedBoth(Port(33434), Port(3500)))
//!     .build()?
//!     .run_with(|round| println!("{:?}", round))?;
//! # Ok(())
//! # }
//! ```
