Perform a write of up to 4096 bytes, and then flush the stream. Block
until all of these operations are complete, or an error occurs. Read more
source§fn write_zeroes(&mut self, nelem: usize) -> StreamResult<()>
fn write_zeroes(&mut self, nelem: usize) -> StreamResult<()>
Repeatedly write a byte to a stream.
Important: this write must be non-blocking!
Returning an Err which downcasts to a
StreamError
will be
reported to Wasm as the empty error result. Otherwise, errors will trap.source§fn blocking_write_zeroes_and_flush<'life0, 'async_trait>(

Simultaneously waits for this stream to be writable and then returns how
much may be written or the last error that happened.
