#[non_exhaustive]pub enum CanonicalSequenceMutation {
Rewind {
common_ancestor: Option<BlockRef>,
dropped: Vec<BlockRef>,
},
Canonical(BlockRef),
Safe(BlockRef),
Finalized(BlockRef),
}Expand description
Cache-free canonical transition proven by validate_canonical_sequence.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Rewind
Rewind the listed retained identities and continue from common_ancestor.
Fields
§
common_ancestor: Option<BlockRef>Surviving canonical anchor, when one is retained or authenticated.
None is a transient same-envelope state: callers must stage the
complete validation atomically and may checkpoint only the returned
next_state, after a later canonical mutation installs the proven
replacement.
Canonical(BlockRef)
Accept or enrich one canonical identity.
Safe(BlockRef)
Accept a safe-head update with metadata resolved against prior state.
Finalized(BlockRef)
Accept a finalized-head update with metadata resolved against prior state.
