WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable target for compilation of high-level languages like C/C++/Rust, enabling deployment on the web for client and server applications.

Problem:
After using Engine.createTextureFromKtx/jpeg/Png, I need to query the texture width and height so I can generate proper UV coordinates for font display.

Proposed solution
Expose the Texture.getWidth(), getHeight(), etc. methods to get texture information. I currently only need width and height, but I can see usage cases for many of the other "getters" available in the C++ in

  • copy/v86#431
  • copy/v86#333 (add a mute button and/or fix the "requires a gesture" warning). A volume selector would also be nice.
  • There's a minor issue where holding down and moving the mouse on the screen selects text outside of the screen on Firefox
  • Retry XHR requests that fail with 5xx or time out, with exponential backoff
  • Add configuration via url parameters (http

Seems like an oversight on our part.

I'm imagining that we would

  1. Make the default amount of fuel 0 in the CLI
  2. Add a --add-fuel <N> option to add N fuel to the store

I think (1) miiiiight be slightly controversial? As an alternative, we would have a --set-fuel <N> option, instead of --add-fuel <N>, and then we would have to ensure that the store gets exactly N fuel rathe

Motivation

I am using the following pattern to efficiently initialize a large buffer inside wasm memory from JavaScript without copies (see #1079 for full motivation):

#[wasm_bindgen]
pub struct WasmMemBuffer {
    buffer: Vec<u8>,
}

#[wasm_bindgen]
impl WasmMemBuffer {
    #[wasm_bindgen(constructor)]
    pub fn new(byte_length: u32, f: &js_sys::Function) -> Self {

Related to metering wasm3/wasm3#127 and being able to run a set number of instructions, I'd like to be able to serialize a paused interpreter's state and deserialize it to a new interpreter instance; very roughly,

const interp = new wasm3.Interpreter(module);
interp.interpretNInstructions(100);
const interpState = interp.serializeState();
const interp2 = wasm3.In
