Little bit of a trick I discovered for documenting fields which are on multiple structures:
```rust
macro_rules! extensions_doc {
() => {
r#"The extensions properties are implemented as patterned fields that are always prefixed by `"x-"`."#
};
}pub struct Info {
// ...
#[doc = extensions_doc!()]
pub extensions: HashMap<String, Value>,
}
```
