Destroy a stream.
This module is meant to ensure a stream gets destroyed, handling different APIs
and Node.js bugs.
## API
```js
var destroy = require('destroy')
```
### destroy(stream [, suppress])
Destroy the given stream, and optionally suppress any future `error` events.
In most cases, this is identical to a simple `stream.destroy()` call. The rules
are as follows for a given stream:
1. If the `stream` is an instance of `ReadStream`, then call `stream.destroy()`
and add a listener to the `open` event to call `stream.close()` if it is
fired. This is for a Node.js bug that will leak a file descriptor if
`.destroy()` is called before `open`.
2. If the `stream` is an instance of a zlib stream, then call `stream.destroy()`
and close the underlying zlib handle if open, otherwise call `stream.close()`.
This is for consistency across Node.js versions and a Node.js bug that will
leak a native zlib handle.
3. If the `stream` is not an instance of `Stream`, then nothing happens.
4. If the `stream` has a `.destroy()` method, then call it.
The function returns the `stream` passed in as the argument.
## Example
```js
var destroy = require('destroy')
var fs = require('fs')
var stream = fs.createReadStream('package.json')
// ... and later
destroy(stream)
```
