Basic instrumentation profiler for Rust
// Based on https://gist.github.com/TheCherno/31f135eea6ee729ab5f26a6908eb3a5e
// Usage:
// 1. Call init before doing anything else with this file/snippet.
// 2. Put `let _timer = Timer::new()` at the begining of any scope you want to measure (DO NOT name the variable `_`. Because it will be dropped instantly after creation.)
// 3. Drag result.json into chrome://tracing (If you have a chromium-based browser) or https://ui.perfetto.dev for visualization
static mut TIMER: Option<std::time::Instant> = None;
static mut OUT_STREAM: String = String::new();
static mut NOT_FIRST: bool = false;
