}

A structure to list and prune previously executed denunciations

Fields

config: ExecutedDenunciationsConfig

Executed denunciations configuration

db: ShareableMassaDBController

Access to the RocksDB database

sorted_denunciations: BTreeMap<Slot, HashSet<DenunciationIndex>>

for better pruning complexity

denunciation_index_serializer: DenunciationIndexSerializer

for rocksdb serialization

denunciation_index_deserializer: DenunciationIndexDeserializer

for rocksdb deserialization

Implementations

impl ExecutedDenunciations

pub fn new( config: ExecutedDenunciationsConfig, db: ShareableMassaDBController, ) -> Self

Create a new ExecutedDenunciations

pub fn recompute_sorted_denunciations(&mut self)

Recomputes the local caches after bootstrap or loading the state from disk

pub fn reset(&mut self)

Reset the executed denunciations

USED FOR BOOTSTRAP ONLY

pub fn contains(&self, de_idx: &DenunciationIndex) -> bool

Check if a denunciation (e.g. a denunciation index) was executed

pub fn apply_changes_to_batch( &mut self, changes: ExecutedDenunciationsChanges, slot: Slot, batch: &mut DBBatch, )

Apply speculative operations changes to the final executed denunciations state

fn prune_to_batch(&mut self, slot: Slot, batch: &mut DBBatch)

Prune all denunciations that have expired, assuming the given slot is final

fn put_entry(&self, de_idx: &DenunciationIndex, batch: &mut DBBatch)

Add a denunciation_index to the DB

Arguments

• de_idx
• batch: the given operation batch to update

fn delete_entry(&self, de_idx: &DenunciationIndex, batch: &mut DBBatch)

Remove a denunciation_index from the DB

Arguments

• de_idx: the denunciation index to remove
• batch: the given operation batch to update

pub fn is_key_value_valid( &self, serialized_key: &[u8], serialized_value: &[u8], ) -> bool

Deserializes the key and value, useful after bootstrap

Trait Implementations

impl Clone for ExecutedDenunciations

fn clone(&self) -> ExecutedDenunciations

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
