Struct data_pile::Database [−][src]
Append-only database. Can be safely cloned and used from different threads.
Implementations
impl Database[src]
pub fn file<P: AsRef<Path>>(path: P) -> Result<Self, Error>[src]
Open the database. Will create one if not exists.
pub fn memory() -> Result<Self, Error>[src]
Open an in-memory database.
pub fn append(&self, records: &[&[u8]]) -> Result<(), Error>[src]
Write an array of records to the database. This function will block if another write is still in progress.
pub fn put(&self, record: &[u8]) -> Result<(), Error>[src]
Put a single record (not recommended).
pub fn get_by_seqno(&self, seqno: usize) -> Option<SharedMmap>[src]
Get a record by its sequential number.
pub fn iter_from_seqno(&self, seqno: usize) -> Option<SeqNoIter>[src]
Iterate records in the order they were added starting form the given sequential number.
