Storage component.

Implementations

source

impl Storage

source

pub fn new(
 cfg: &WithDir<Config>,
 hard_reset_to_start_of_era: Option<EraId>,
 protocol_version: ProtocolVersion,
 should_check_integrity: bool,
 network_name: &str
) -> Result<Self, Error>

Creates a new storage component.

If should_check_integrity is true, time-consuming integrity checks will be performed during this call to new(), potentially blocking for several minutes. This should normally only be required if the node is detected to have restarted after a crash.

source

pub fn put_deploy(&self, deploy: &Deploy) -> Result<bool, Error>

Put a single deploy into storage.

source

pub fn read_block(&self, block_hash: &BlockHash) -> Result<Option<Block>, Error>

Retrieves a block by hash.

source

pub fn read_deploy_by_hash(
&self,
deploy_hash: DeployHash
) -> Result<Option<Deploy>, Error>

Directly returns a deploy from internal store.

source

pub fn write_block(&mut self, block: &Block) -> Result<bool, Error>

Writes a block to storage, updating indices as necessary Returns Ok(true) if the block has been successfully written, Ok(false) if a part of it couldn’t be written because it already existed, and Err(_) if there was an error.

source

pub fn read_block_by_height(&self, height: u64) -> Result<Option<Block>, Error>

Retrieves single block by height by looking it up in the index and returning it.

source

pub fn read_highest_block(&self) -> Result<Option<Block>, Error>

Gets the highest block.

source

pub fn store_finalized_approvals(
 &self,
 deploy_hash: &DeployHash,
 finalized_approvals: &FinalizedApprovals
) -> Result<(), Error>

Stores a set of finalized approvals.

source

impl Storage

source

pub fn transactional_get_switch_block_by_era_id(
&self,
switch_block_era_num: u64
) -> Option<Block>

Get the switch block for a specified era number in a read-only LMDB database transaction.

Panics

Panics on any IO or db corruption error.
