.infer(obj) ⇒ Object

Try to find a sedes objects suitable for a given Ruby object.

The sedes objects considered are ‘obj`’s class, ‘big_endian_int` and `binary`. If `obj` is a list, a `RLP::Sedes::List` will be constructed recursively.

Parameters:

  • obj (Object) —

    the Ruby object for which to find a sedes object

Raises:

  • (TypeError) —

    if no appropriate sedes could be found
