WURST

Webby DOM abstraction of web-sys.

Project Aims

• Wrap all the DOM APIs and provide an ergonomic easy to use library
• Provide compile time checking of Front End code.
• Have an escape hatch to the DOM for runtime checking.
• Provide a zero cost abstraction on top of the DOM

Setup

Currently this code is only tested with Nighly and the latest wasm-bindgen.

Given we are in an unreleased state at the moment, please enusre you have the latest wasm-bindgen binary:

rustup update
cargo install -f wasm-bindgen-cli

To enable well formatted generated code:

export WEBIDL_RUSTFMT_BINDINGS=1;

I'm also only checking this on Nightly at the moment. Other builds may work.

Example

Form Example

To run a demo server:

cd examples/form-example/;
source build.sh

Usage

Current usage of the library:

let mut div = create_element!("div", {
    // Element interface
    id: "Boop",

    // HTMLElement interface
    title: "hey I am a title",
    lang: "en-GB"
});
div.create();
div.add_to_body();

let mut input = create_element!("input", {
    // Element interface
    id: "Boop",

    // Input interface
    value: "hey!",

    // HTMLElement interface
    title: "2323",
    lang: "boom"
});
input.create();
input.add_to_body();

input.attrs.id = Some("boo".into());
input.update();

The above code internally will return an El which implements an Elementish field trait. The concrete types are DivElement and InputElement respectively.

The macro will only accept what the concrete interface will accept. So providing the wrong element attributes to the macro will fail at compile time:

error[E0560]: struct `wurst::elements::DivElement` has no field named `value`
  --> src/main.rs:20:9
   |
20 |         value: "my value"
   |         ^^^^^ `wurst::elements::DivElement` does not have this field
   |
   = note: available fields are: `title`, `lang`, `dir`, `inner_text`, `access_key` ... and 3 others

error: aborting due to previous error
