Mojo JS bindings: draining a DataPipe (Closed)
DescriptionMojo JS bindings: draining a DataPipe
Add a drainData(dataPipeHandle) utility function to the Mojo JS core module.
The drainData() function asynchronously reads from the data pipe until the remote handle is closed or an error occurs. A Promise is returned whose settled value is an object like this: {result: core.RESULT_OK, buffer: dataArrayBuffer}. If the read failed, then the result will be the actual error code and the buffer will contain whatever was read before the error occurred. The drainData dataPipeHandle argument is closed automatically.
