Struct UnifiedStorageWriter

Source 
pub struct UnifiedStorageWriter<'a, ProviderDB, ProviderSF> { /* private fields */ }
Expand description

UnifiedStorageWriter is responsible for managing the writing to storage with both database and static file providers.

Implementations§

Source§

impl<'a, ProviderDB, ProviderSF> UnifiedStorageWriter<'a, ProviderDB, ProviderSF>

Source

pub const fn new( database: &'a ProviderDB, static_file: Option<ProviderSF>, ) -> Self

Creates a new instance of UnifiedStorageWriter.

§Parameters
  • database: An optional reference to a database provider.
  • static_file: An optional mutable reference to a static file instance.
Source

pub fn from<P>(database: &'a P, static_file: ProviderSF) -> Self
where P: AsRef<ProviderDB>,

Creates a new instance of UnifiedStorageWriter from a database provider and a static file instance.

Source

pub fn from_database<P>(database: &'a P) -> Self
where P: AsRef<ProviderDB>,

Creates a new instance of UnifiedStorageWriter from a database provider.

Source§

impl UnifiedStorageWriter<'_, (), ()>

Source

pub fn commit<P>(provider: P) -> ProviderResult<()>
where P: DBProvider<Tx: DbTxMut> + StaticFileProviderFactory,

Commits both storage types in the right order.

For non-unwinding operations it makes more sense to commit the static files first, since if it is interrupted before the database commit, we can just truncate the static files according to the checkpoints on the next start-up.

NOTE: If unwinding data from storage, use commit_unwind instead!

Source

pub fn commit_unwind<P>(provider: P) -> ProviderResult<()>
where P: DBProvider<Tx: DbTxMut> + StaticFileProviderFactory,

Commits both storage types in the right order for an unwind operation.

For unwinding it makes more sense to commit the database first, since if it is interrupted before the static files commit, we can just truncate the static files according to the checkpoints on the next start-up.

NOTE: Should only be used after unwinding data from storage!

impl<ProviderDB> UnifiedStorageWriter<'_, ProviderDB, &StaticFileProvider<ProviderDB::Primitives>>
where ProviderDB: DBProvider<Tx: DbTx + DbTxMut> + BlockWriter + TransactionsProviderExt + TrieWriter + StateWriter + HistoryWriter + StageCheckpointWriter + BlockExecutionWriter + AsRef<ProviderDB> + StaticFileProviderFactory,

Source

pub fn save_blocks<N>( &self, blocks: Vec<ExecutedBlock<N>>, ) -> ProviderResult<()>
where N: NodePrimitives<SignedTx: SignedTransaction>, ProviderDB: BlockWriter<Block = N::Block> + StateWriter<Receipt = N::Receipt>,

Writes executed blocks and receipts to storage.

Source

pub fn remove_blocks_above(&self, block_number: u64) -> ProviderResult<()>

Removes all block, transaction and receipt data above the given block number from the database and static files. This is exclusive, i.e., it only removes blocks above block_number, and does not remove block_number.
