Module stream 

Node stream module: native base classes + module helper functions.

The base classes (Readable/Writable/Duplex/Transform/PassThrough/ Stream) are EventEmitter-backed objects (same @@native/@@on/@@once shape as net sockets) exposing the surface higher layers touch today: on/once/emit, write/end, push/read, and a best-effort pipe. http’s req/res are their own native objects (see http.rs); this module exists so require('stream') yields the base constructors and the module helper functions (finished, pipeline, isReadable, …).

Lifecycle state is tracked with hidden boolean props set as terminal events fire: @@ended (readable end), @@finished (writable finish), @@destroyed (close/destroy), @@errored (error value), @@disturbed (read/resume/pipe). finished(stream, cb) callbacks live in a @@finished array drained on the first terminal event so the callback fires exactly once.

Constants

CLASSES

The base classes exported by require('stream').

METHODS

The module free-functions exported by require('stream').

STATIC_METHODS

Statics on the stream CONSTRUCTORS (Readable.from, not stream.from).

Functions

call

Module free-function dispatch (stream.finished, stream.isReadable, …).

constant

stream.<Class> property (a constructor value), reachable via namespace_property → stdlib::constant.

construct

new Readable() / Writable / Duplex / Transform / PassThrough / Stream.

flush_from

Drain a Readable.from queue: one data per item, then end.

instance_call

Instance dispatch for a stream base class. EventEmitter methods are delegated to events; emit routes through emit_event for lifecycle tracking.

is_class

True if name is one of the stream base-class constructors.

static_call

Readable.from(iterable) / Duplex.from(iterable).

transform_callback

The callback a transform implementation invokes: cb(err, chunk). A nullish chunk contributes nothing, matching push(null)-style suppression.
