Struct WasmModule 

#[repr(C)]
pub struct WasmModule {
    pub vtable_: *const WasmModule__bindgen_vtable,
    pub _base: AtomicRefCounted,
}

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.

Trait Implementations

impl Debug for WasmModule

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for WasmModule

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

Tests for self and other values to be equal, and is used by ==.

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

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

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
