Struct VsdbBlockStore 

pub struct VsdbBlockStore { /* private fields */ }

Persistent block store backed by vsdb

Implementations

impl VsdbBlockStore

pub fn open(data_dir: &Path) -> Result<Self>

Opens an existing block store or creates a fresh one.

Must be called after vsdb::vsdb_set_base_dir. The instance IDs of the internal collections are stored in data_dir/block_store.meta. On first run the file is created; on subsequent runs the collections are recovered from saved IDs.

Backward-compatible: 24-byte meta (v1, 3 collections) is auto-migrated to 40 bytes (v2, 5 collections) on first open.

pub fn new() -> Self

Creates a new in-memory block store without any persistent meta file. Intended for unit tests only; use Self::open in production.

pub fn contains(&self, hash: &BlockHash) -> bool

pub fn flush(&self)

Trait Implementations

impl BlockStore for VsdbBlockStore

fn put_block(&mut self, block: Block)

fn get_block(&self, hash: &BlockHash) -> Option<Block>

fn get_block_by_height(&self, h: Height) -> Option<Block>

fn get_blocks_in_range(&self, from: Height, to: Height) -> Vec<Block>

Get blocks in [from, to] inclusive. Default iterates one-by-one.

fn tip_height(&self) -> Height

Return the highest stored block height.

fn put_commit_qc(&mut self, height: Height, qc: QuorumCertificate)

Store the QC that committed a block at the given height.

fn get_commit_qc(&self, height: Height) -> Option<QuorumCertificate>

Retrieve the commit QC for a block at the given height.

fn flush(&self)

Flush pending writes to durable storage.

fn put_tx_index(&mut self, tx_hash: [u8; 32], height: Height, index: u32)

Store a tx hash → (height, index) mapping.

fn get_tx_location(&self, tx_hash: &[u8; 32]) -> Option<(Height, u32)>

Look up a tx hash → (height, index_in_block).

fn put_block_results(&mut self, height: Height, results: EndBlockResponse)

Store the EndBlockResponse for a given height.

fn get_block_results(&self, height: Height) -> Option<EndBlockResponse>

Retrieve the EndBlockResponse for a given height.

impl Default for VsdbBlockStore

fn default() -> Self

Returns the “default value” for a type.
