Mappable | flexible JSON to Model converter | JSON Processing library

Instead of creating a whole custome cmap, I got rid of this piece of code:

I don't know how to constrain T to be a variant of Definition.

There is no such thing in Rust. There's the name of the variant and the name of the type contained within that variant, there is no relationship between the two. The variants can be named whatever they want, and multiple variant can contain the same type. So there's no shorthand for pulling a T out of an enum which has a variant with a T.

You need to make your own trait that says how to get a T from a Definition:

The example you cite does not use a location argument to colorbar:

The issue is related to SDN not working properly.

As a general rule, troubleshooting this, we would check the SDN pods (calico, weave, or in this case flannel), are they healthy, any errors in their logs, ...

Check iptables (iptables -nL) and ipvs (ipvsadm -l n) configuration nodes.

Restart SDN pods, as well as kube-proxy, if you still didn't find anything.

Now, on this specific case, we're not suffering from an outage: cluster is freshly deployed, it's likely the SDN never worked at all - though this may not be obvious, with a kubeadm deployment, that doesn't ship with other pods than the defaults, most of which using host networking.

The kubeadm init command mentions that pod CIDR is some 192.168.5.0/24, which brings two remarks:

• with all SDN: the pod CIDR is a subnet that will be split into smaller subnets (usually /24 or /25). Each range being statically allocated to Nodes when they first join your cluster

• running flannel SDN: kubeadm init should include a --pod-network-cidr argument that MUST match the subnet configured in the kube-flannel-cfg ConfigMap, see net-conf.json key.

Though I'm unfamiliar with the process of fixing this, there seem to be an answer on ServerFault that gives some instructions, which sounds right: https://serverfault.com/a/977401/293779

I believe typescript wants your CustomMap to extend google.maps.Map. But since you seem to be using composition, I guess you'll have to proxy all those methods.

The answer to your question as asked is probably "anything else you do to verify the types of those static properties will be more involved than what you're already doing, so you might as well keep doing that".

TypeScript doesn't have a simple way to verify that a value is assignable to some type without generally widening it to that type. You'd like to say something like

Using the latest matplotlib version (3.4.2), the code seems to work as expected.

I don't understand what's the Mapper object is. It can be done with Codable.

You can do like this to update your local config with incoming config.

Its Array of dictionaries try to type cast as [[String: Any]]

Now there is no need of external mapper frameworks Apple is providing Codable which is easy to use and easy to understand the errors in parsing as well.
