Struct snarkos_storage::LedgerStorage [−][src]
pub struct LedgerStorage { /* fields omitted */ }
Implementations
Opens storage from the given path with its given names. If storage does not exists, it creates a new storage file at the given path with its given names, and opens it. If RocksDB fails to open, returns StorageError.
pub fn open_secondary_cf<P: AsRef<Path> + Clone>(
primary_path: P,
secondary_path: P,
num_cfs: u32
) -> Result<Self, StorageError>
pub fn open_secondary_cf<P: AsRef<Path> + Clone>(
primary_path: P,
secondary_path: P,
num_cfs: u32
) -> Result<Self, StorageError>
Opens a secondary storage instance from the given path with its given names. If RocksDB fails to open, returns StorageError.
Trait Implementations
Opens the storage object, optionally using the given paths; it gets created if it doesn’t exist.
Returns the value with the given key and belonging to the given column.
Returns all the keys and values belonging to the given column.
Returns all the keys belonging to the given column.
Stores the given key and value in the specified column.
Executes the given DatabaseTransaction
as a batch operation.
Returns true
if the given key exists in the speficied column.
