[calvinbrown085]

This fixes conflicts introduced here.
#60

All credit goes to @jdeschenes for implementing the original feature.

I'm not exactly sure what went wrong with the build here..

[calvinbrown085]

@poros Do you know what went wrong on the build? It looks like cargo check worked fine.

[poros]

I am not really sure what the first error is, perhaps something transient caused by travis? Anyways, I have re-started the build and it fails with compilation errors. Maybe you can try to run make test locally and see if your branch works on your machine?

[codehearts]

It looks like you just forgot to use serde::Serialize; in the test module of de.rs, the other two things were deprecation warnings that shouldn't break the stable and nightly builds

[calvinbrown085]

@codehearts Thanks! I must have missed that when fixing merge conflicts

[codehearts]

Ah, now it looks like cargo fmt needs to be run on the repo for the build to be happy

[calvinbrown085]

@codehearts I will grab this later tonight :)

[poros]

@calvinbrown085 are you still interested in this PR? It was pretty close to land!

[calvinbrown085]

@poros Yes! I will grab this.

[calvinbrown085]

@poros Okay I ran cargo fmt lets see if this passes :)

[calvinbrown085]

@poros Anything else here?

[poros]

Nothing else, thanks :)
