You mean fmt.Fprintf right? Formatting a string without writing to a io.Writer (fmt.Sprintf) must be safe for concurrent use.
The "log" package should be safe for concurrent use, and has a Printf function: https://godoc.org/log#Logger """ A Logger represents an active logging object that generates lines of output to an io.Writer. Each logging operation makes a single call to the Writer's Write method. A Logger can be used simultaneously from multiple goroutines; it guarantees to serialize access to the Writer.
