Struct Repository

pub struct Repository { /* private fields */ }

A repository. All operations on repositories must be done via transactions.

Implementations

impl Repository

pub fn open<P: AsRef<Path>>(path: P, size_increase: Option<u64>) -> Result<Self>

Open a repository, possibly increasing the size of the underlying file if size_increase is Some(…).

pub unsafe fn open_nolock<P: AsRef<Path>>( path: P, size_increase: Option<u64>, ) -> Result<Self>

Open a repository, possibly increasing the size of the underlying file if size_increase is Some(…).

pub unsafe fn close(&mut self)

Close a repository. It is undefined behaviour to use it afterwards.

pub fn txn_begin(&self) -> Result<Txn<'_>>

Start an immutable transaction. Immutable transactions can run concurrently.

pub fn mut_txn_begin<R: Rng>(&self, r: R) -> Result<MutTxn<'_, R>>

Start a mutable transaction. Mutable transactions exclude each other, but can in principle be run concurrently with immutable transactions. In that case, the immutable transaction only have access to the state of the repository immediately before the mutable transaction started.
