## hyperdrive binary search

Find files by name in a [hyperdrive](https://github.com/mafintosh/hyperdrive), using binary search.

This implementation has no dependencies, and is a tiny port of the [binary-search](https://www.npmjs.com/package/binary-search) package to work with hyperdrive archives.

### Usage

```js

var hypersearch = require('hyperdrive-binary-search')

hypersearch(archive, 'myfile.txt', (err, entry) => {

  if (err) raise err

  console.log(entry)

})

```

The second argument to the callback (here called `entry`) is a hyperdrive metadata entry, e.g.:

```json

{

  "type": "file",

  "name": "myfile.txt",

  "mode": 33188,

  "size": 5028864,

  "uid": 0,

  "gid": 0,

  "mtime": 0,

  "ctime": 0

}

```

you can download the corresponding file from the archive, e.g:

```js

hypersearch(archive, 'myfile.txt', (err, entry) => {

  if (err) raise err

  var progress = archive.download(entry)

})

```
