Functions

func FromContext

func FromContext(ctx context.Context) *slog.Logger

FromContext returns the a logger instance, either a newly initialised logger if one doesn't exist, a fieldless logger if the provided context is nil, or a logger retrieved from the provided context.

The ability to call FromContext with a nil context and get a clean logger instance eliminates the need for a logging.New() constructor.

func New

func New() *slog.Logger

func ToContext

func ToContext(ctx context.Context, args ...any) (*slog.Logger, context.Context)

ToContext adds the provided fields to the logger returned by WithContext, then stores it in the provided context against the loggerKey key.
