Implementations

impl AcidStorage

pub fn new( root_dir: impl Into<PathBuf>, shard_count: usize, max_total_bytes: u64, max_stream_bytes: u64, ) -> Result<Self>

Errors

Returns Error::Storage if storage layout validation fails, shard databases cannot be opened, or on-disk recovery cannot complete.

pub fn total_bytes(&self) -> u64
