- Directory structure changed slightly
- Uses a filter_map instead of a for loop.
- All errors reading files does not prevent others from being read.
- The accounts manager needs to generate files first, with the same structure.
- Custom datadir/server argument logic moved into configuration, out of main.
- Updated the validator config directory structure, as per issue #253 suggestions
- Removed the 'generate 3 random keys' function
- Updated the README to reflect new structure
- Just exit if there are no keys, don't generate any (this is for accounts_manager, in a separate commit).
- Created a lib.rs file, so that the validator client configuration can be included by external crates.
- Creates a keystore directory in the config
- Fetches serialized keys from the keystore directory
- If no keys, generates keys randomly, saves serialized keys to keystore dir.
