NAME

BSON - Pure Perl implementation of MongoDB's BSON serialization

VERSION

version 0.12

SYNOPSIS

    use BSON qw/encode decode/;

    my $document = {
        _id      => BSON::ObjectId->new,
        date     => BSON::Time->new,
        name     => 'James Bond',
        age      => 45,
        amount   => 24587.45,
        badass   => BSON::Bool->true,
        password => BSON::String->new('12345')
    };

    my $bson = encode( $document );
    my $doc2 = decode( $bson, %options );

DESCRIPTION

This module implements BSON serialization and deserialization as described at http://bsonspec.org. BSON is the primary data representation for MongoDB.

EXPORT

The module does not export anything. You have to request encode and/or decode manually.

    use BSON qw/encode decode/;

SUBROUTINES

encode

Takes a hashref and returns a BSON string.

    my $bson = encode({ bar => 'foo' });

decode

Takes a BSON string and returns a hashref.

    my $hash = decode( $bson, ixhash => 1 );

The options after $bson are optional and they can be any of the following:

options

  1. ixhash => 1|0

    If set to 1 decode will return a Tie::IxHash ordered hash. Otherwise, a regular unordered hash will be returned. Turning this option on entails a significant speed penalty as Tie::IxHash is slower than a regular Perl hash. The default value for this option is 0.

THREADS

This module is thread safe.

LIMITATION

MongoDB sets a limit for any BSON record to 16MB. This module does not enforce this limit and you can use it to encode and decode structures as large as you please.

CAVEATS

BSON uses zero terminated strings and Perl allows the \0 character to be anywhere in a string. If you expect your strings to contain \0 characters, use BSON::Binary instead.

HISTORY AND ROADMAP

This module was originally written by minimalist. In 2014, he graciously transferred ongoing maintenance to MongoDB, Inc.

Going forward, work will focus on restoration of a pure-Perl dependency chain, harmonization with MongoDB driver BSON classes and some API enhancements so this can provide a pure-Perl alternative serializer for the MongoDB driver.
