Functions

func GetContextMap

func GetContextMap(ctx context.Context) (m *sync.Map, ok bool)

GetContextMap returns the sync.Map in the given context

func WithContextMap

func WithContextMap(ctx context.Context) context.Context

WithContextMap returns a new context that carries a sync.Map It's useful if you want to share a sync.Map between middlewares, especially for Middleware and RecvMiddleware/SendMiddleware, since in recv/send middlewares, we can only get the stream.Context() which is a fixed node in the context tree.

Note: it's not added to context by default, and you should add it yourself if needed.
