func FlushWithHTTPResponse

func FlushWithHTTPResponse(ctx context.Context, response *HTTPResponse)

func Info

func Info(ctx context.Context, message interface{})

Example

sn := dogtime.StockNower{}
dogtime.SetNower(&sn)

now := time.Date(2019, 1, 2, 3, 4, 5, 6, time.UTC)
sn.AddStockTime(now)

ctx := slog.WithValue(context.Background())
slog.Info(ctx, slog.KV{"hoge", "fuga"})
slog.Flush(ctx)

Output:
