Seeing error when trying to serialize an enum with rmp-serde

[crhino]

I am trying to serialize an enum with rmp-serde and I am running into an error:

`Err` value: DeserializeError(Syntax("syntax error: expected an enum"))`

which seems to come from serde's default implementation of visit_enum.

I see that you have tests surround serializing enums, which is almost exactly what I am trying to do. I am wondering if there is something that I am missing here. Taking a look at your Travis builds it does not seem like those tests are being run there.

I already have serde_macros enabled and have custom_derive and plugin features, not sure what else I need.

Any help would be much appreciated!

Figured out how to get the tests running, looks like they have the same failure.

Sorry for a long waiting.

My fault - currently enum deserializing is broken (and untested due to forgotten --features option). I'll try to fix it today.

[3Hren]

Please take a look at #44. It should fix your issues.

[crhino]

@3Hren Looks good! Thanks.

[3Hren]

Resolved with #44.
