Hello,
I'm trying to read gob-encoded data into a variable of interface type. In
simple cases, this works for me, but when I use a custom encoding
via MarshalBinary() and UnmarshalBinary() methods, my code keeps crashing,
with the error message
panic: interface conversion: interface is nil, not
encoding.BinaryUnmarshaler
Example:
- The code at https://play.golang.org/p/y8nWNhObUwb, letting gob do the
en-/decoding works.
- The very similar code at https://play.golang.org/p/-zS7QjEJg9x, which
uses MarshalBinary() and UnmarshalBinary() crashes with the panic shown
above.
What am I doing wrong?
[I asked the same question at https://stackoverflow.com/questions/57485698/,
with no answers so far]
Many thanks,
Jochen
