[GuillaumeGomez]

Is this intermittent?

[emilio]

Nope, and I think those are suspicious enough to deserve a bit of investigation. They're most likely caused by this changeset.

However I don't understand what you want:

and please add some unions with dictionaries to TestBinding so these paths are tested.

[nox]

Which part do you not understand?

This patch makes Servo cope with unions including a dictionary type, so I want TestBinding (see TestBinding.webidl) to include some stuff with such unions.

[GuillaumeGomez]

I added @Ms2ger's suggestion.

[GuillaumeGomez]

Appveyor error is: "error: failed to build archive: bad archive: permission denied". Intermittent failure?

Because in case of errors, it returns None instead of an error so I tried to keep the same logic.

When the trait returns `Err(())`, it threw something. So you need to throw on `ConversionResult::Failure` too otherwise it makes no sense.
