//! pprof-rs is an integrated profiler for rust program.
//!
//! This crate provides a programable interface to start/stop/report a profiler dynamically. With the
//! help of this crate, you can easily integrate a profiler into your rust program in a modern, convenient
//! way.
//!
//! A sample usage is:
//!
//! ```rust
//! let guard = pprof::ProfilerGuard::new(100).unwrap();
//! ```
//!
//! Then you can read report from the guard:
//!
//! ```rust
//! # let guard = pprof::ProfilerGuard::new(100).unwrap();
//!if let Ok(report) = guard.report().build() {
//!    println!("report: {:?}", &report);
//!};
//! ```
