Expand description
A minimal “state backend” trait: an abstraction over the sources of data a blockchain state may draw upon.
Currently assumes a very specific DB + cache structure, but should become general over time to the point where not even a merkle trie is strictly necessary.
Structs
A basic backend. Just wraps the given database, directly inserting into and deleting from it. Doesn’t cache anything.
A raw backend used to check proofs of execution.
Proving state backend.
This keeps track of all state values loaded during usage of this backend.
The proof-of-execution can be extracted with extract_proof.
Traits
State backend. See module docs for more details.
