gob: type elliptic.p256Curve has no exported fields about blockchain_go HOT 20 OPEN

from blockchain_go.

elliptic.p256Curve should have no exported fields, right? Because of p being lowercase. Inspecting further.

from blockchain_go.

Here is why. https://cs.opensource.google/go/go/+/refs/tags/go1.19.4:src/crypto/elliptic/nistec.go;l=35;drc=38cfb3be9d486833456276777155980d1ec0823e

The field is not accessible outside the file.

from blockchain_go.

Yup, i inspected until this point, but can we do any work around this ?

For context, https://stackoverflow.com/questions/32676898/whats-the-purpose-of-gob-register-method
The problem is saving the wallets map so that we can always reconstruct the data... Just thinking out loud.

from blockchain_go.

One way might be to create your own type/interface to access to field...

Yup, i will try to create interface and i will comment or probably create PR for this . Thanks @BryceWayne

Here is my workaround (see lns 89-143). Then remove ln 66 and ln 82 from wallets.go.

I implemented GobEncoder/GobDecoder interfaces to the Wallet struct so gob.Register(elliptic.P256()) can be removed.

Seems @LangLiBa this repo is outdated, i created this issue long ago, there is no reply. I fixed this by using 1.18.9 go version.
I could have pursued to fix this, but my objective was to learn blockchain, not to fix this
