Struct EthStateCache

pub struct EthStateCache { /* private fields */ }

Provides async access to cached eth data

This is the frontend for the async caching service which manages cached data on a different task.

Implementations

impl EthStateCache

pub fn spawn<Provider, EvmConfig>( provider: Provider, config: EthStateCacheConfig, evm_config: EvmConfig, ) -> Self

where Provider: StateProviderFactory + BlockReader + EvmEnvProvider + Clone + Unpin + 'static, EvmConfig: ConfigureEvm<Header = Header>,

Creates a new async LRU backed cache service task and spawns it to a new task via [tokio::spawn].

See also Self::spawn_with

pub fn spawn_with<Provider, Tasks, EvmConfig>( provider: Provider, config: EthStateCacheConfig, executor: Tasks, evm_config: EvmConfig, ) -> Self

where Provider: StateProviderFactory + BlockReader + EvmEnvProvider + Clone + Unpin + 'static, Tasks: TaskSpawner + Clone + 'static, EvmConfig: ConfigureEvm<Header = Header>,

Creates a new async LRU backed cache service task and spawns it to a new task via the given spawner.

The cache is memory limited by the given max bytes values.

pub async fn get_sealed_block_with_senders( &self, block_hash: B256, ) -> ProviderResult<Option<Arc<SealedBlockWithSenders>>>

Requests the [SealedBlockWithSenders] for the block hash

Returns None if the block does not exist.

pub async fn get_receipts( &self, block_hash: B256, ) -> ProviderResult<Option<Arc<Vec<Receipt>>>>

Requests the [Receipt] for the block hash

Returns None if the block was not found.

pub async fn get_block_and_receipts( &self, block_hash: B256, ) -> ProviderResult<Option<(Arc<SealedBlockWithSenders>, Arc<Vec<Receipt>>)>>

Fetches both receipts and block for the given block hash.

pub async fn get_evm_env( &self, block_hash: B256, ) -> ProviderResult<(CfgEnvWithHandlerCfg, BlockEnv)>

Requests the evm env config for the block hash.

Returns an error if the corresponding header (required for populating the envs) was not found.
