There was a problem hiding this comment.
Creating this struct with Default will initialize everything to zero, including the attempts_number. Shouldn't that be at least 1 by default?

This PR introduces a new crate with the primitives required by #41.
Quoting the crate README:
Nevertheless, the strategy here is to incrementally drain the main Sassafras PR by upstreaming smaller components in order to make the overall protocol inclusion and analysis more manageable.
The structures and functions were found to satisfy the requirements of the protocol.
A more in depth analysis of the structures obviously requires to dig into the client and frame pallets in the main PR.
This crate requires to enable bandersnatch-experimental feature in some of its dependencies.
This feature ends up being transitively enabled in:
sp-consensus-sassafras → sp-application-crypto → sp-io → sp-keystore
Follows that Bandersnatch API ends up being exposed by the
Keystoretrait and thus we require to expose these functions implementations in the client keystore (sc-keystore) as well.The (temporary)
workaround is to includesolution is to conditionally compilesc-keystoreas an optional dependency insp-consensus-sassafrasand enable it withbandersnatch-experimentalfeature on std buildssc-keystoreexperimental code using the result ofgenerate_feature_enabled_macro(see 3a1eeda)Step towards: #41
