Componenta Stream Iterator
==========================

[](#componenta-stream-iterator)

Iterator for reading PSR-7 streams in fixed-size chunks.

Use it for uploads, downloads, hashing, conversion, and other streaming workflows where loading the full body into memory is unnecessary.

Installation
------------

[](#installation)

```
composer require componenta/stream-iterator
```

Requires `psr/http-message`.

Related Packages
----------------

[](#related-packages)

PackageWhy it matters here`psr/http-message``StreamIterator` reads PSR-7 `StreamInterface`.`psr/http-message`Uploads, downloads, and request bodies can expose PSR-7 streams.`componenta/iterator`Use it when replayable iteration is needed; stream iteration keeps only the current chunk.`componenta/image-converter`Upload streams can be read before media processing.Usage
-----

[](#usage)

```
use Componenta\Stdlib\StreamIterator;

$iterator = new StreamIterator($stream, bytesPerIteration: 1024);

foreach ($iterator as $offset => $chunk) {
    // $offset is the stream position where the chunk started.
}
```

Contract
--------

[](#contract)

`StreamIterator` implements `Iterator` and `Stringable`.

Important behavior:

- `current()` is idempotent
- reading happens during `rewind()` and `next()`
- repeated calls to `current()` do not consume more bytes
- `key()` returns the chunk start offset
- `withStream()` and `withBytes()` return cloned iterators
- `setBytes()` mutates bytes-per-iteration on the current instance

Memory Model
------------

[](#memory-model)

The iterator keeps only the current chunk. It does not cache previous chunks and does not make a one-shot stream replayable. Use `componenta/iterator` if you need replayable iteration.
