Package trace
Overview
Go execution tracer. The tracer captures a wide range of execution events like goroutine creation/blocking/unblocking, syscall enter/exit/block, GC-related events, changes of heap size, processor start/stop, etc and writes them to an io.Writer in a compact form. A precise nanosecond-precision timestamp and a stack trace is captured for most events. A trace can be analyzed later with 'go tool trace' command.
