Implementations

impl LmdbBlockStore

pub fn new(root_path: &Path, total_size: usize) -> Result<Self, BlockStoreError>

pub fn write_finality_signatures( &self, txn: &mut RwTransaction<'_>, signatures: &BlockSignatures, ) -> Result<BlockHash, BlockStoreError>

Write finality signatures.

Trait Implementations

impl BlockStoreProvider for LmdbBlockStore

type Reader<'t> = LmdbBlockStoreTransaction<'t, RoTransaction<'t>>

Reader alias.

type ReaderWriter<'t> = LmdbBlockStoreTransaction<'t, RwTransaction<'t>>

ReaderWriter alias.

fn checkout_ro(&self) -> Result<Self::Reader<'_>, BlockStoreError>

Check out read only handle.

fn checkout_rw(&mut self) -> Result<Self::ReaderWriter<'_>, BlockStoreError>

Check out read write handle.

impl DataSize for LmdbBlockStore

const IS_DYNAMIC: bool = true

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = 0usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for LmdbBlockStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
