## NAME
    [BSON::String](https://www.chedong.com/phpMan.php/perldoc/BSON%3A%3AString/markdown) - BSON type wrapper for strings

## VERSION
    version v1.12.2

## SYNOPSIS
        use [BSON::Types](https://www.chedong.com/phpMan.php/perldoc/BSON%3A%3ATypes/markdown) ':all';

        bson_string( $string );

## DESCRIPTION
    This module provides a BSON type wrapper for a string value.

    Since Perl does not distinguish between numbers and strings, this module provides an explicit
    string type for a scalar value.

## ATTRIBUTES
  value
    A scalar value, which will be stringified during construction. The default is the empty string.

## METHODS
  TO_JSON
    Returns value as a string.

## OVERLOADING
    The stringification operator ("") is overloaded to return the "value", the full "minimal set" of
    overloaded operations is provided (per overload documentation) and fallback overloading is
    enabled.
