#initialize(mongocrypt, io, doc) ⇒ ExplicitDecryptionContext

Create a new ExplicitDecryptionContext object

Parameters:

  • mongocrypt (Mongo::Crypt::Handle) —

    a Handle that wraps a mongocrypt_t object used to create a new mongocrypt_ctx_t

  • io (ClientEncryption::IO) —

    A instance of the IO class that implements driver I/O methods required to run the state machine

  • doc (BSON::Document) —

    A document to decrypt

Instance Method Details

#bson_mode ⇒ Symbol?

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Which BSON mode to use when creating documents from the outcome of the state machine. The returned value is based on the Mongo::Config.csfle_convert_to_ruby_types option.

Returns:

  • (Symbol, nil) —

    The BSON mode.
