EctoSparkles.ErlangTermBinary (ecto_sparkles v0.1.1)
A custom Ecto type for handling the serialization of arbitrary data types stored as binary data in the database. Requires the underlying DB field to be a binary.

Functions
Callback implementation for Ecto.Type.cast/1.
Provides custom casting rules for params. Nothing changes here. We only need to handle deserialization.
Converting the data structure to binary for storage.
Callback implementation for Ecto.Type.embed_as/1.
Callback implementation for Ecto.Type.equal?/2.
Convert the raw binary value from the database back to the desired term.
Callback implementation for Ecto.Type.type/0.

cast(term)
Callback implementation for Ecto.Type.cast/1.
cast(atom, term)
Provides custom casting rules for params. Nothing changes here. We only need to handle deserialization.
dump(term)
Converting the data structure to binary for storage.
embed_as(_)
Callback implementation for Ecto.Type.embed_as/1.
equal?(term1, term2)
Callback implementation for Ecto.Type.equal?/2.
load(raw_binary)
Convert the raw binary value from the database back to the desired term.
Uses Plug.Crypto.non_executable_binary_to_term/2 - a restricted version of :erlang.binary_to_term/2 that forbids executable terms, such as anonymous functions.
By default this function does not restrict atoms, except if compiled in prod env, then the [:safe] option is set, so only existing (and loaded) atoms will be deserialized.
type()
Callback implementation for Ecto.Type.type/0.
