Expand description
Node stream/promises module: the Promise-based finished and pipeline.
require('stream/promises') exposes promise-returning versions of
stream.finished and stream.pipeline. Rather than duplicate the listener
bookkeeping already in stream.rs, each wraps the callback-based
require('stream') free function in a Promise — the same compile-a-JS-factory
technique util.promisify uses (crate::compile_completion + load_merged +
host::run_chunk_on, then invoke the factory).
The returned promise is a REAL pending promise: stream.finished(stream, cb)
registers listeners and drains its callback on the first terminal event
(end/finish/close) or on error, at which point the callback settles the
promise. A stream that has ALREADY reached a terminal state settles immediately
(the callback-based finished fires synchronously in that case). No faked
resolution — a stream that never terminates leaves the promise pending, exactly
as Node does.
