Bug description
I would like to pass data from host to as using host bindings. On the as side the target class is extending another class.
Steps to reproduce
Target class:
export class Foo {
a: i32 = 0
}
export class Baa extends Foo {
b: i32 = 0
}index.ts (AS)
export function test(test: Baa): void {
console.log('test')
}Calling from host side:
...
wasm.test({a: 0, b: 1})
...I get a runtime error like that:
Uncaught (in promise) TypeError: internref expected at __lowerInternref (release.js?t=1725378963979:80:11) at Object.test (release.js?t=1725378963979:37:14) ....
Generated glue code is not looking as expected:
declare namespace __AdaptedExports {
/** Exported memory */
export const memory: WebAssembly.Memory;
/**
* assembly/index/test
* @param test `assembly/Baa`
*/
export function test(test: __Internref16): void;
}
/** assembly/Baa */
declare class __Internref16 extends Number {
private __nominal16: symbol;
private __nominal17: symbol;
private __nominal0: symbol;
}
/** Instantiates the compiled WebAssembly module with the given imports. */
export declare function instantiate(module: WebAssembly.Module, imports: {
env: unknown,
}): Promise<typeof __AdaptedExports>;Removing inheritance from target class is solving the problem:
export class Baa { a: i32 = 0 b: i32 = 0 }
Is inheritance not supported for host bindings?
