pub struct Handle { /* private fields */ }

Implementations

impl Handle

pub fn set_instance_limits(&mut self, limits: Limits) -> Result<()>

pub fn dir(&self) -> &PathBuf

pub fn new(dir: PathBuf) -> Result<Self>

pub fn block_size(&self) -> u64

pub fn new_writer(&self) -> Result<BatchWriter<'_>>

pub fn start_deferred_transaction_for_read(&self) -> Result<OwnedReadTx<'_>>

Starts a deferred transaction (the default). There is no guaranteed read-only transaction mode. There might be pragmas that can limit to read only statements.

pub fn read(&self) -> Result<Reader<'_>>

Begins a read transaction.

pub fn read_single(&self, key: &[u8]) -> Result<Option<SnapshotValue<Value>>>

pub fn single_write_from( &self, key: Vec<u8>, r: impl Read ) -> Result<(u64, WriteCommitResult)>

pub fn single_delete(&self, key: &[u8]) -> PubResult<Option<PossumStat>>

pub fn clone_from_fd(&mut self, key: Vec<u8>, fd: RawFd) -> Result<u64>

pub fn rename_item(&mut self, from: &[u8], to: &[u8]) -> PubResult<Timestamp>

pub fn walk_dir(&self) -> Result<Vec<WalkEntry>>

Walks the underlying files in the possum directory.

pub fn list_items(&self, prefix: &[u8]) -> PubResult<Vec<Item>>
