pub struct WasmModule { pub vtable_: *const WasmModule__bindgen_vtable, pub _base: AtomicRefCounted, }
Expand description

The WasmModule interface allows the embedding to hold a reference to the underying C++ implementation of a JS WebAssembly.Module object for purposes of efficient postMessage() and (de)serialization from a random thread.

In particular, this allows postMessage() of a WebAssembly.Module: GetWasmModule() is called when making a structured clone of a payload containing a WebAssembly.Module object. The structured clone buffer holds a refcount of the JS::WasmModule until createObject() is called in the target agent’s JSContext. The new WebAssembly.Module object continues to hold the JS::WasmModule and thus the final reference of a JS::WasmModule may be dropped from any thread and so the virtual destructor (and all internal methods of the C++ module) must be thread-safe.

fn eq(&self, other: &WasmModule) -> bool

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
