pub fn write_query<W: Write + ?Sized>(output: &mut W) -> Result<()>Expand description
Writes an optional feature query without reading input or imposing a timeout. This function does not flush the writer.
Route replies through the TUI’s existing input reader and parser::Decoder.
A bare query and a default reply have identical bytes; use stream direction
and a pending-query flag to distinguish them.
§Errors
Returns the writer’s I/O error.
