With Rust 1.26 we got nicer match bindings. For details see the URL field.

What looks kinda helpful is that it can be simplified a lot when using a reference. Here an example:

Before: 

> impl ToJson for NullActionItem {
>     fn to_json(&self) -> Json {
>         match self {
>             &NullActionItem::General(ref x) => x.to_json(),
>         }
>     }
> }

After:

> impl ToJson for NullActionItem {
>     fn to_json(&self) -> Json {
>         match self {
>             NullActionItem::General(x) => x.to_json(),
>         }
>     }
> }

A separate bug can be filed for mozbase-rust crates.
