DataCodingStrategy

public enum DataCodingStrategy : RawRepresentable

Enum representing the various encoding/decoding strategy pairs for Dates. Set these on a MongoClient, MongoDatabase, or MongoCollection so that the strategies will be applied when converting Datas between their BSON representations and their representations in (non BSONDocument) Codable types.

As per the BSON specification, the default strategy is to encode Datas as BSON binary types with the generic binary subtype.

  • Encode/decode the Data by deferring to its default encoding implementations.

    Note: The default encoding implementation attempts to encode the Data as a [UInt8], but because BSON does not support integer types besides Int32 or Int64, it actually gets encoded to BSON as an [Int32]. This results in a space inefficient storage of the Data (using 4 bytes of BSON storage per byte of data).

  • Encode the Data to/from a base64 encoded string.

  • Encode the Data by using the given encodeFunc. Decode the Data by using the given decodeFunc. If encodeFunc does not encode a value, an empty document will be encoded in its place.
