Detailed Description

BSON support.

Function Documentation

◆ ArrayFromJsonString()

Value formats::bson::ArrayFromJsonString ( std::string_view json )

Applies heuristics to convert JSON string to BSON array. As JSON have rather lax typing, some heuristics are applied to guess correct BSON types for values. It is strongly recommended to write your own conversion routines matching your schemas.

Warning: Stability of heuristics is not guaranteed, this is provided as-is.

◆ FromJsonString()

Document formats::bson::FromJsonString ( std::string_view json )

Applies heuristics to convert JSON string to BSON document. As JSON have rather lax typing, some heuristics are applied to guess correct BSON types for values. It is strongly recommended to write your own conversion routines matching your schemas.

Warning: Stability of heuristics is not guaranteed, this is provided as-is.

◆ ToArrayJsonString()

JsonString formats::bson::ToArrayJsonString ( const formats::bson::Value & )

Converts BSON array to a legacy libbson's JSON format, except the outermost element is encoded as a JSON array, rather than a JSON document.

◆ ToCanonicalJsonString()

JsonString formats::bson::ToCanonicalJsonString ( const formats::bson::Document & )

Converts BSON to a canonical MongoDB Extended JSON format.

See also: https://github.com/mongodb/specifications/blob/master/source/extended-json.rst

◆ ToLegacyJsonString()

JsonString formats::bson::ToLegacyJsonString ( const formats::bson::Document & )

Converts BSON to a legacy libbson's JSON format. Notable differences from other formats:

all numbers are not wrapped;
non-standard tokens for special floating point values;
dates are milliseconds since epoch;
different format for binaries.

◆ ToRelaxedJsonString()

JsonString formats::bson::ToRelaxedJsonString ( const formats::bson::Document & )

Converts BSON to a relaxed MongoDB Extended JSON format. Notable differences from canonical format are:

numbers are not being wrapped in $number* objects;
dates have string representation.
