type Logger ¶

type Logger struct {
	Enabled bool
	W       io.Writer
	// contains filtered or unexported fields
}

Logger writes verbose diagnostic messages when Enabled is true. Output goes to the configured writer (typically stderr).

Printf is safe for concurrent use: the parallel lint pipeline can reach a shared logger from many goroutines, and not every io.Writer (e.g. bytes.Buffer) is itself thread-safe. mu serializes the format + write so lines are never torn or dropped. Always use *Logger; copying a Logger value would copy the mutex.

func (l *Logger) Printf(format string, args ...any)
