Implementations

impl TestStageDB

pub fn new(path: &Path) -> Self

pub fn commit<F>(&self, f: F) -> ProviderResult<()>

where F: FnOnce(&<DatabaseEnv as Database>::TXMut) -> ProviderResult<()>,

Invoke a callback with transaction committing it afterwards

pub fn query<F, Ok>(&self, f: F) -> ProviderResult<Ok>

where F: FnOnce(&<DatabaseEnv as Database>::TX) -> ProviderResult<Ok>,

Invoke a callback with a read transaction

pub fn table_is_empty<T: Table>(&self) -> ProviderResult<bool>

Check if the table is empty

pub fn table<T: Table>(&self) -> ProviderResult<Vec<KeyValue<T>>>

where T::Key: Default + Ord,

Return full table as Vec

pub fn ensure_no_entry_above<T, F>( &self, num: u64, selector: F, ) -> ProviderResult<()>

where T: Table, F: FnMut(T::Key) -> BlockNumber,

Check that there is no table entry above a given number by Table::Key

pub fn ensure_no_entry_above_by_value<T, F>( &self, num: u64, selector: F, ) -> ProviderResult<()>

where T: Table, F: FnMut(T::Value) -> BlockNumber,

Check that there is no table entry above a given number by Table::Value

pub fn insert_header<TX: DbTx + DbTxMut>( writer: Option<&mut StaticFileProviderRWRefMut<'_, ()>>, tx: &TX, header: &SealedHeader, td: U256, ) -> ProviderResult<()>

Insert header to static file if writer exists, otherwise to DB.

pub fn insert_headers<'a, I>(&self, headers: I) -> ProviderResult<()>

where I: IntoIterator<Item = &'a SealedHeader>,

Insert ordered collection of [SealedHeader] into the corresponding static file and tables that are supposed to be populated by the headers stage.

pub fn insert_headers_with_td<'a, I>(&self, headers: I) -> ProviderResult<()>

where I: IntoIterator<Item = &'a SealedHeader>,

Inserts total difficulty of headers into the corresponding static file and tables.

Superset functionality of TestStageDB::insert_headers.

pub fn insert_blocks<'a, I>( &self, blocks: I, storage_kind: StorageKind, ) -> ProviderResult<()>

where I: IntoIterator<Item = &'a SealedBlock>,

Insert ordered collection of [SealedBlock] into corresponding tables. Superset functionality of TestStageDB::insert_headers.

If tx_offset is set to None, then transactions will be stored on static files, otherwise database.

Assumes that there’s a single transition for each transaction (i.e. no block rewards).

pub fn insert_tx_hash_numbers<I>( &self, tx_hash_numbers: I, ) -> ProviderResult<()>

where I: IntoIterator<Item = (TxHash, TxNumber)>,

pub fn insert_receipts<I>(&self, receipts: I) -> ProviderResult<()>

where I: IntoIterator<Item = (TxNumber, Receipt)>,

Insert collection of ([TxNumber], [Receipt]) into the corresponding table.

pub fn insert_receipts_by_block<I, J>( &self, receipts: I, storage_kind: StorageKind, ) -> ProviderResult<()>

where I: IntoIterator<Item = (BlockNumber, J)>, J: IntoIterator<Item = (TxNumber, Receipt)>,

Insert collection of ([TxNumber], [Receipt]) organized by respective block numbers into the corresponding table or static file segment.

pub fn insert_transaction_senders<I>( &self, transaction_senders: I, ) -> ProviderResult<()>

where I: IntoIterator<Item = (TxNumber, Address)>,

pub fn insert_accounts_and_storages<I, S>( &self, accounts: I, ) -> ProviderResult<()>

where I: IntoIterator<Item = (Address, (Account, S))>, S: IntoIterator<Item = StorageEntry>,

Insert collection of ([Address], [Account]) into corresponding tables.

pub fn insert_changesets<I>( &self, changesets: I, block_offset: Option<u64>, ) -> ProviderResult<()>

where I: IntoIterator<Item = ChangeSet>,

Insert collection of ChangeSet into corresponding tables.

pub fn insert_history<I>( &self, changesets: I, _block_offset: Option<u64>, ) -> ProviderResult<()>

where I: IntoIterator<Item = ChangeSet>,
