Implementations§

Source§

impl<N: NodePrimitives> StaticFileProviderRW<N>

Source

pub fn new( segment: StaticFileSegment, block: BlockNumber, reader: Weak<StaticFileProviderInner<N>>, metrics: Option<Arc<StaticFileProviderMetrics>>, ) -> ProviderResult<Self>

Creates a new StaticFileProviderRW for a [StaticFileSegment].

Before use, transaction based segments should ensure the block end range is the expected one, and heal if not. For more check Self::ensure_end_range_consistency.

Source

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

Commits configuration changes to disk and updates the reader index with the new changes.

Source

pub fn commit_without_sync_all(&mut self) -> ProviderResult<()>

Available on crate feature test-utils only.

Commits configuration changes to disk and updates the reader index with the new changes.

CAUTION: does not call sync_all on the files.

Source

pub fn increment_block( &mut self, expected_block_number: BlockNumber, ) -> ProviderResult<()>

Allows to increment the [SegmentHeader] end block. It will commit the current static file, and create the next one if we are past the end range.

Returns the current [BlockNumber] as seen in the static file.

Source

pub fn append_header( &mut self, header: &N::BlockHeader, total_difficulty: U256, hash: &BlockHash, ) -> ProviderResult<()>
where N::BlockHeader: Compact,

Appends header to static file.

It CALLS increment_block() since the number of headers is equal to the number of blocks.

Returns the current [BlockNumber] as seen in the static file.

Source

pub fn append_transaction( &mut self, tx_num: TxNumber, tx: &N::SignedTx, ) -> ProviderResult<()>
where N::SignedTx: Compact,

Appends transaction to static file.

It DOES NOT CALL increment_block(), it should be handled elsewhere. There might be empty blocks and this function wouldn’t be called.

Returns the current [TxNumber] as seen in the static file.

Source

pub fn append_receipt( &mut self, tx_num: TxNumber, receipt: &N::Receipt, ) -> ProviderResult<()>
where N::Receipt: Compact,

Appends receipt to static file.

It DOES NOT call increment_block(), it should be handled elsewhere. There might be empty blocks and this function wouldn’t be called.

Returns the current [TxNumber] as seen in the static file.

Source

pub fn append_receipts<I, R>( &mut self, receipts: I, ) -> ProviderResult<Option<TxNumber>>
where I: Iterator<Item = Result<(TxNumber, R), ProviderError>>, R: Borrow<N::Receipt>, N::Receipt: Compact,

Appends multiple receipts to the static file.

Returns the current [TxNumber] as seen in the static file, if any.

Source

pub fn prune_transactions( &mut self, to_delete: u64, last_block: BlockNumber, ) -> ProviderResult<()>

Adds an instruction to prune to_deletetransactions during commit.

Note: last_block refers to the block the unwinds ends at.

Source

pub fn prune_receipts( &mut self, to_delete: u64, last_block: BlockNumber, ) -> ProviderResult<()>

Adds an instruction to prune to_delete receipts during commit.

Note: last_block refers to the block the unwinds ends at.

Source

pub fn prune_headers(&mut self, to_delete: u64) -> ProviderResult<()>

Adds an instruction to prune to_delete headers during commit.

Source

pub const fn user_header(&self) -> &SegmentHeader

Helper function to access [SegmentHeader].

Source

pub fn user_header_mut(&mut self) -> &mut SegmentHeader

Helper function to access a mutable reference to [SegmentHeader].

Source

pub fn set_block_range(&mut self, block_range: RangeInclusive<BlockNumber>)

Available on crate feature test-utils only.

Helper function to override block range for testing.

Source

pub fn inner(&mut self) -> &mut NippyJarWriter<SegmentHeader>

Available on crate feature test-utils only.

Helper function to override block range for testing.
