Struct ProviderFactory

Source 
pub struct ProviderFactory<N: NodeTypesWithDB> { /* private fields */ }
Expand description

A common provider that fetches data from a database or static file.

This provider implements most provider or provider factory traits.

Implementations§

Source§

impl<N: NodeTypesWithDB> ProviderFactory<N>

Source

pub fn new( db: N::DB, chain_spec: Arc<N::ChainSpec>, static_file_provider: StaticFileProvider<N::Primitives>, ) -> Self

Create new database provider factory.

Source

pub fn with_static_files_metrics(self) -> Self

Enables metrics on the static file provider.

Source

pub fn with_prune_modes(self, prune_modes: PruneModes) -> Self

Sets the pruning configuration for an existing ProviderFactory.

Source

pub const fn db_ref(&self) -> &N::DB

Returns reference to the underlying database.

Source

pub fn into_db(self) -> N::DB

Available on crate feature test-utils only.

Consumes Self and returns DB

Source§

impl<N: NodeTypesWithDB<DB = Arc<DatabaseEnv>>> ProviderFactory<N>

Source

pub fn new_with_database_path<P: AsRef<Path>>( path: P, chain_spec: Arc<N::ChainSpec>, args: DatabaseArguments, static_file_provider: StaticFileProvider<N::Primitives>, ) -> RethResult<Self>

Create new database provider by passing a path. ProviderFactory will own the database instance.

Source§

impl<N: ProviderNodeTypes> ProviderFactory<N>

Source

pub fn provider(&self) -> ProviderResult<DatabaseProviderRO<N::DB, N>>

Returns a provider with a created DbTx inside, which allows fetching data from the database using different types of providers. Example: HeaderProvider BlockHashReader. This may fail if the inner read database transaction fails to open.

This sets the [PruneModes] to None, because they should only be relevant for writing data.

Source

pub fn provider_rw(&self) -> ProviderResult<DatabaseProviderRW<N::DB, N>>

Returns a provider with a created DbTxMut inside, which allows fetching and updating data from the database using different types of providers. Example: HeaderProvider BlockHashReader. This may fail if the inner read/write database transaction fails to open.

Source

pub fn latest(&self) -> ProviderResult<StateProviderBox>

Source

pub fn history_by_block_number( &self, block_number: BlockNumber, ) -> ProviderResult<StateProviderBox>

Storage provider for state at that given block

Source

pub fn history_by_block_hash( &self, block_hash: BlockHash, ) -> ProviderResult<StateProviderBox>
