NAME

Mango::BSON - BSON

SYNOPSIS

  use Mango::BSON ':bson';

  my $bson = bson_encode {
    foo       => 'bar',
    baz       => 0.42,
    unordered => {one => [1, 2, 3], two => bson_time},
    ordered   => bson_doc(one => qr/test/i, two => bson_true)
  };
  my $doc = bson_decode $bson;

DESCRIPTION

Mango::BSON is a minimalistic implementation of http://bsonspec.org.

In addition to a bunch of custom BSON data types it supports normal Perl data types like Scalar, Regexp, undef, Array reference, Hash reference and will try to call the TO_JSON method on blessed references, or stringify them if it doesn't exist. Scalar references will be used to generate booleans, based on if their values are true or false.

FUNCTIONS

Mango::BSON implements the following functions, which can be imported individually or at once with the :bson flag.

bson_bin

  my $bin = bson_bin $bytes;

Create new BSON element of the binary type with Mango::BSON::Binary, defaults to the generic binary subtype.

  # Function
  bson_bin($bytes)->type('function');

  # MD5
  bson_bin($bytes)->type('md5');

  # UUID
  bson_bin($bytes)->type('uuid');

  # User defined
  bson_bin($bytes)->type('user_defined');

bson_code

  my $code = bson_code 'function () {}';

Create new BSON element of the code type with Mango::BSON::Code.

  # With scope
  bson_code('function () {}')->scope({foo => 'bar'});

bson_dbref

  my $dbref = bson_dbref('test', $oid);

Create a new database reference.

bson_decode

  my $doc = bson_decode $bson;

Decode BSON into Perl data structures.

bson_doc

  my $doc = bson_doc;
  my $doc = bson_doc foo => 'bar', baz => 0.42, yada => {yada => [1, 2, 3]};

Create new BSON document with Mango::BSON::Document, which can also be used as a generic ordered hash.

  # Order is preserved
  my $hash = bson_doc one => 1, two => 2, three => 3;
  $hash->{four} = 4;
  delete $hash->{two};
  say for keys %$hash;

bson_encode

  my $bson = bson_encode $doc;
  my $bson = bson_encode {};

Encode Perl data structures into BSON.

bson_false

  my $false = bson_false;

Create new BSON element of the boolean type false.

bson_length

  my $len = bson_length $bson;

Check BSON length prefix.

bson_max

  my $max_key = bson_max;

Create new BSON element of the max key type.

bson_min

  my $min_key = bson_min;

Create new BSON element of the min key type.

bson_oid

  my $oid = bson_oid;
  my $oid = bson_oid '1a2b3c4e5f60718293a4b5c6';

Create new BSON element of the object id type with Mango::BSON::ObjectID, defaults to generating a new unique object id.

  # Generate object id with specific epoch time
  my $oid = bson_oid->from_epoch(1359840145);

bson_time

  my $now  = bson_time;
  my $time = bson_time time * 1000;

Create new BSON element of the UTC datetime type with Mango::BSON::Time, defaults to milliseconds since the UNIX epoch.

bson_true

  my $true = bson_true;

Create new BSON element of the boolean type true.

bson_ts

  my $timestamp = bson_ts 23, 24;

Create new BSON element of the timestamp type with Mango::BSON::Timestamp.

decode_int32

  my $int32 = decode_int32 $bytes;

Decode 32bit integer.

decode_int64

  my $int64 = decode_int64 $bytes;

Decode 64bit integer.

encode_cstring

  my $bytes = encode_cstring $cstring;

Encode cstring.

encode_int32

  my $bytes = encode_int32 $int32;

Encode 32bit integer.

encode_int64

  my $bytes = encode_int64 $int64;

Encode 64bit integer.
