A Model<T> stores a reference to a External<Rc<ModelNotify>>.
Every time such a Model<T> needs to be exposed to Slint/Rust, we create
a TypedRustModel that wraps the Rc<ModelNotify>, a strong reference to
the JS object, and the Type field for the expected data type (the
interpreter expects). The Model trait is implemented on TypedRustModel,
which means it is allocated every time the conversion is needed, but the
underlying Rc<ModelNotify> is shared and thus the (forwarded) ModelNotify.
When converting back to JavaScript, we downcast_ref to the
TypedRustModel and fetch the original JavaScript object - if available.
- Instead of building index.js with esbuild and generating types with
tsc, use tsc to build index.js and index.d.ts.
- Use ts-node instead of swc for typescript based tests, as that
works with es modules.
- Remove "syntax_check" target from package.json as that's now
implied with "compile".
- Sadly this requires one "as any" cast as tsc somehow fails to
determine the right type info for node-fetch.
Unfortunately index.js can't be an ES module without breaking
compatiblity. It would imply that the Node.js port can't be used with
require() anymore. So even thought that would simplify things further,
it's not part of this PR.
