Functions

func LoggerFrom

func LoggerFrom(ctx context.Context, keyvals ...interface{}) kitlog.Logger

LoggerFrom retrieves the stashed logger from a context, as put there by WithLogger

func StartSpan

func StartSpan(ctx context.Context, name string, opts ...trace.StartOption) (context.Context, *trace.Span, kitlog.Logger)

StartSpan extends the opencensus method so it stashes a logger into the context, and annotates the logger with the current trace ID. If a logger was never provided, we use a no-op logger.

func WithLogger

func WithLogger(ctx context.Context, logger kitlog.Logger, keyvals ...interface{}) (context.Context, kitlog.Logger)

WithLogger configures a logger that can be retrived with LoggerFrom.
