Overview … The same Context may be passed to functions running in different goroutines; Contexts are safe for simultaneous use by multiple goroutines. Contexts are built using layers. Every time you call one of the context.With* functions, the orginal context is wrapped in a new layer. This is the “magic” that makes contexts concurrency safe by design–they’re never mutated once they’re created. ctx := context.Background() // Create an original context ctx, cancel = context.
