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.

~WasmStreaming | ( | ) |
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.
void Finish | ( | ) |
{Finish} should be called after all received bytes where passed to {OnBytesReceived} to tell V8 that there will be no more bytes. {Finish} does not have to be called after {Abort} has been called already.
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.
void SetClient | ( | std::shared_ptr< Client > | client | ) |
Sets the client object that will receive streaming event notifications. This must be called before {OnBytesReceived}, {Finish}, or {Abort}.
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.
void SetUrl | ( | const char * | url, |
size_t | length | ||
) |
|
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.
