goid

Documentation

Overview

Package goid returns the current goroutine's ID.

Get() is on the hottest path in the interpreter: every dynamic-var deref (Var.getDynamicBinding) and every thread-binding push/pop/clone keys off it. On supported configurations (see goid_fast.go) it is a two-instruction read of the runtime g struct's goid field; everywhere else it falls back to parsing runtime.Stack() output (getSlow below, the original vendored implementation). Selection is compile-time via build tags — ADR 0034.

func Get() int64

Get returns the current goroutine's ID via the runtime.Stack() text-parse — the portable fallback for arches or toolchains the fast path (goid_fast.go) has not been vetted on. Slow but always correct.
