pub type OutputStream = Box<dyn HostOutputStream>;Expand description
An output bytestream.
output-streams are non-blocking to the extent practical on
underlying platforms. Except where specified otherwise, I/O operations also
always return promptly, after the number of bytes that can be written
promptly, which could even be zero. To wait for the stream to be ready to
accept data, the subscribe function to obtain a pollable which can be
polled for using wasi:io/poll.
Dropping an output-stream while there’s still an active write in
progress may result in the data being lost. Before dropping the stream,
be sure to fully flush your writes.
