How can I use WebGL extensions from web_sys in Rust

I'd like to use WebGL Extensions from within Rust code that is compiled to WebAssembly. The web_sys::WebGlRenderingContext has a method get_extension which returns a JsValue.

I expect there is a way to either use the dyn_into method to get an ANGLE_instanced_arrays interface, which according to this webidl may be included in web_sys somewhere, but I can't seem to get at it. If it's not possible to get to the ANGLE_instanced_arrays interface, is it possible to call known methods and properties using the JsValue directly?

Solution

  • As per this issue: wasm-bindgen issue 893 - Figure out how to support interfaces with NoInterfaceObject attribute The WebGL extensions should be available in the next release.
