ConvertBSONValueToJSON walks through a document or an array and converts any BSON value to its corresponding extended JSON type.

ConvertJSONDocumentToBSON iterates through the document map and converts JSON values to their corresponding BSON values.

ConvertJSONValueToBSON walks through a document or an array and replaces any extended JSON value with its corresponding BSON type.

FindValueByKey returns the value of keyName in document.

GetBSONValueAsJSON is equivalent to ConvertBSONValueToJSON, but does not mutate its argument.

GetExtendedBsonD iterates through the document and returns a bson.D that adds type information for each key in document.

MakeSortString takes a bson.D object and converts it to a slice of strings that can be used as the input args to mgo's .Sort(...) function.

ParseJSONValue takes any value generated by the json package and returns a BSON version of that value.

ParseSpecialKeys takes a JSON document and inspects it for any extended JSON type (e.g $numberLong) and replaces any such values with the corresponding BSON type.

MarshalD is a wrapper for bson.D that allows unmarshalling of bson.D with preserved order.
