A procedural macro for compiling jsx into a DomElement type

#![feature(proc_macro, proc_macro_non_items)]

extern crate jsx_types;
extern crate jsx_macro;

let on_click: Box<jsx_types::EventHandler> = Box::new(|_| println!("foo!"));
let subtitle = "This is a subtitle";
let dom = jsx!(<div foo="bar">
  <h1 OnClick={on_click}>This title is clickable</h1>
  <div class="subtitle">{ subtitle }</div>
</div>);

• This is the main crate, which exports the jsx! and jsx_verbose! macros.

• This macro exports all of the used types: HtmlToken, DomElement, EventName, Event, EventHandler, Attributes and EventHandlers.

• Tests the jsx_macro crate.

• Add RustDoc docs
• DomElement.event_handlers is not done correctly. For example, an OnClick handlers and an OnMouseOver handlers should receive different events. Thus, DomElement should have separate, optional fields, e.g.:

pub type DomElement {
  // ... other fields
  on_click: Option<Box<FnOnce(ClickEvent) -> ()>>,
  on_mouseover: Option<Box<FnOnce(MouseEvent) -> ()>>,
}

• There should be also be a builder-pattern constructor for DomElement.
• Integrate with a wasm full-stack app.
• Other methods: to_inner_html and the like.
• Spacing on multiline idents and such
