/**
* An "async function" in the context of Async is an asynchronous function with
* a variable number of parameters, with the final parameter being a callback.
* (`function (arg1, arg2, ..., callback) {}`)
* The final callback is of the form `callback(err, results...)`, which must be
* called once the function is completed. The callback should be called with a
* Error as its first argument to signal that an error occurred.
* Otherwise, if no error occurred, it should be called with `null` as the first
* argument, and any additional `result` arguments that may apply, to signal
* successful completion.
* The callback must be called exactly once, ideally on a later tick of the
* JavaScript event loop.
*
* This type of function is also referred to as a "Node-style async function",
* or a "continuation passing-style function" (CPS). Most of the methods of this
* library are themselves CPS/Node-style async functions, or functions that
* return CPS/Node-style async functions.
*
* Wherever we accept a Node-style async function, we also directly accept an
* [ES2017 `async` function]{@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function}.
* In this case, the `async` function will not be passed a final callback
* argument, and any thrown error will be used as the `err` argument of the
* implicit callback, and the return value will be used as the `result` value.
* (i.e. a `rejected` of the returned Promise becomes the `err` callback
* argument, and a `resolved` value becomes the `result`.)
*
* Note, due to JavaScript limitations, we can only detect native `async`
* functions and not transpilied implementations.
* Your environment must have `async`/`await` support for this to work.
* (e.g. Node > v7.6, or a recent version of a modern browser).
* If you are using `async` functions through a transpiler (e.g. Babel), you
* must still wrap the function with [asyncify]{@link module:Utils.asyncify},
* because the `async function` will be compiled to an ordinary function that
* returns a promise.
*
* @typedef {Function} AsyncFunction

// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.
