Functions

func Log

func Log(ctx context.Context, args ...any)

Log writes args to the log.Logger previously attached to ctx. If no logger is attached, writes nothing.

func Logf

func Logf(ctx context.Context, format string, args ...any)

Logf is like Log but uses fmt.Sprintf.

func LoggerContext

func LoggerContext(ctx context.Context, lg *log.Logger) context.Context

LoggerContext attaches lg to a new context derived from ctx. The returned context can later be passed to Log or Logf.
