Struct DatabaseProviderRW 

Source 
pub struct DatabaseProviderRW<DB: Database, N: NodeTypes>(pub DatabaseProvider<<DB as Database>::TXMut, N>);
Expand description

A DatabaseProvider that holds a read-write database transaction.

Ideally this would be an alias type. However, there’s some weird compiler error (https://github.com/rust-lang/rust/issues/102211), that forces us to wrap this in a struct instead. Once that issue is solved, we can probably revert back to being an alias type.

Implementations§

Source§

impl<DB: Database, N: NodeTypes + 'static> DatabaseProviderRW<DB, N>

Source

pub fn commit(self) -> ProviderResult<()>

Commit database transaction and static file if it exists.

Source

pub fn into_tx(self) -> <DB as Database>::TXMut

Consume DbTx or DbTxMut.

Source

pub const fn with_minimum_pruning_distance(self, distance: u64) -> Self

Available on crate features test-utils only.

Override the minimum pruning distance for testing purposes.

Methods from Deref<Target = DatabaseProvider<<DB as Database>::TXMut, N>>§

Source

pub fn prune_modes_ref(&self) -> &PruneModes

Returns reference to prune modes.

Source

pub fn latest<'a>(&'a self) -> Box<dyn StateProvider + 'a>

State provider for latest state

Source

pub fn history_by_block_hash<'a>( &'a self, block_hash: BlockHash, ) -> ProviderResult<Box<dyn StateProvider + 'a>>

Storage provider for state at that given block hash

Source

pub fn set_prune_modes(&mut self, prune_modes: PruneModes)

Available on crate feature test-utils only.

Sets the prune modes for provider.

Source

pub fn with_rocksdb_batch<F, R>(&self, f: F) -> ProviderResult<R>
where F: FnOnce(RocksBatchArg<'_>) -> ProviderResult<(R, Option<RawRocksDBBatch>)>,

Executes a closure with a RocksDB batch, automatically registering it for commit.

This helper encapsulates all the cfg-gated RocksDB batch handling.

Source

pub fn save_blocks( &self, blocks: Vec<ExecutedBlock<N::Primitives>>, save_mode: SaveBlocksMode, ) -> ProviderResult<()>

Writes executed blocks and state to storage.

This method parallelizes static file (SF) writes with MDBX writes. The SF thread writes headers, transactions, senders (if SF), and receipts (if SF, Full mode only). The main thread writes MDBX data (indices, state, trie - Full mode only).

Use SaveBlocksMode::Full for production (includes receipts, state, trie). Use SaveBlocksMode::BlocksOnly for block structure only (used by insert_block).

Source

pub fn unwind_trie_state_from(&self, from: BlockNumber) -> ProviderResult<()>

Unwinds trie state starting at and including the given block.

This includes calculating the resulted state root and comparing it with the parent block state root.

Source

pub fn tx_mut(&mut self) -> &mut TX

Pass DbTx or DbTxMut mutable reference.

Source

pub fn tx_ref(&self) -> &TX

Pass DbTx or DbTxMut immutable reference.

Source

pub fn chain_spec(&self) -> &N::ChainSpec

Returns a reference to the chain specification.
