Implementations§

Source§

impl<N: NodeTypes> ProviderFactory<NodeTypesWithDBAdapter<N, Arc<DatabaseEnv>>>

Source

pub fn builder() -> ProviderFactoryBuilder<N>

Source

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

Returns reference to the underlying database.

Source

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

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.
