# BSON::MinKey(3pm)

BSON type wrapper for MinKey

## NAME

BSON::MinKey - BSON type wrapper for MinKey

## VERSION

version v1.12.2

## SYNOPSIS

```
    use BSON::Types ':all';
    bson_minkey();
```

## DESCRIPTION

This module provides a BSON type wrapper for the special BSON "MinKey" type. The object returned is a singleton.

## METHODS

### TO\_JSON

If the `"BSON_EXTJSON"` option is true, returns a hashref compatible with MongoDB's extended JSON \<https://github.com/mongodb/specifications/blob/master/source/extended-json.rst\> format, which represents it as a document as follows:

```
    {"$minKey" : 1}
```

If the `"BSON_EXTJSON"` option is false, an error is thrown, as this value can't otherwise be represented in JSON.
