Interface WebAssemblyFlags

Set or get a number specifying the timeout for initialization of WebAssembly backend, in milliseconds. A zero value indicates no timeout is set.

set or get number of thread(s). If omitted or set to 0, number of thread(s) will be determined by system. If set to 1, no worker thread will be spawned.

This setting is available only when WebAssembly multithread feature is available in current context.

Set or get a boolean value indicating whether to proxy the execution of main thread to a worker thread.

ONNX Runtime will perform feature detection based on the value of this property. Specifically, when the value is set to:

• undefined, true or "fixed": will check availability of Fixed-width SIMD.
• "relaxed": will check availability of Relaxed SIMD.
• false: will not perform SIMD feature checking.

Setting this property does not make ONNX Runtime to switch to the corresponding runtime automatically. User need to set wasmPaths or wasmBinary property to load the corresponding runtime.

This setting is available only when WebAssembly SIMD feature is available in current context.

set or get a boolean value indicating whether to enable trace.

Set a custom buffer which contains the WebAssembly binary. If this property is set, the wasmPaths property will be ignored.

Set a custom URL prefix to the .wasm/.mjs files, or an object of overrides for both .wasm/.mjs file. The override path should be an absolute path.
