# transient-0

transient-0 is a binary encoding of hobgoblin data is for transient data where
forwards and backwards compatibility is not required, such as IPC between
different instances of the same program.

The encoder and decoder must use the same version of hobgoblin and the same data
definitions for decoding to succeed.

transient-0 does not support:
* Compatibility between different versions of hobgoblin. The exact encoding is
  an implementation detail that may change between any two versions of
  hobgoblin.
* Compatibility between different data definitions. For instance, if a field is
  added to a struct, there is no guarantee that data encoded before the field
  was added can be decoded using the new data definition.
