Detailed Description

The V8 interface for WebAssembly streaming compilation. When streaming compilation is initiated, V8 passes a {WasmStreaming} object to the embedder such that the embedder can pass the input bytes for streaming compilation to V8.

Member Function Documentation

◆ Abort()

void Abort ( MaybeLocal< Value > exception )

Abort streaming compilation. If {exception} has a value, then the promise associated with streaming compilation is rejected with that value. If {exception} does not have value, the promise does not get rejected. {Abort} must not be called repeatedly, or after {Finish}.

◆ Finish()

void Finish ( bool can_use_compiled_module = true )

{Finish} should be called after all received bytes where passed to {OnBytesReceived} to tell V8 that there will be no more bytes. {Finish} must not be called after {Abort} has been called already. If {can_use_compiled_module} is true and {SetCompiledModuleBytes} was previously called, the compiled module bytes can be used. If {can_use_compiled_module} is false, the compiled module bytes previously set by {SetCompiledModuleBytes} should not be used.

◆ OnBytesReceived()

void OnBytesReceived	(	const uint8_t *	bytes,
		size_t	size
	)

Pass a new chunk of bytes to WebAssembly streaming compilation. The buffer passed into {OnBytesReceived} is owned by the caller.

◆ SetCompiledModuleBytes()

bool SetCompiledModuleBytes	(	const uint8_t *	bytes,
		size_t	size
	)

Passes previously compiled module bytes. This must be called before {OnBytesReceived}, {Finish}, or {Abort}. Returns true if the module bytes can be used, false otherwise. The buffer passed via {bytes} and {size} is owned by the caller. If {SetCompiledModuleBytes} returns true, the buffer must remain valid until either {Finish} or {Abort} completes. The compiled module bytes should not be used until {Finish(true)} is called, because they can be invalidated later by {Finish(false)}.

◆ SetMoreFunctionsCanBeSerializedCallback()

void SetMoreFunctionsCanBeSerializedCallback ( std::function< void(CompiledWasmModule)> )

Sets a callback which is called whenever a significant number of new functions are ready for serialization.

◆ SetUrl()

void SetUrl	(	const char *	url,
		size_t	length
	)

◆ Unpack()

static std::shared_ptr< WasmStreaming > Unpack	(	Isolate *	isolate,
		Local< Value >	value
	)

static

Unpacks a {WasmStreaming} object wrapped in a {Managed} for the embedder. Since the embedder is on the other side of the API, it cannot unpack the {Managed} itself.
