Struct thetadb::Options

pub struct Options { /* private fields */ }

The options for configuring a ThetaDB instance.

Implementations

impl Options

pub fn new() -> Self

Creates a new Options instance with default values.

pub fn page_size(&mut self, page_size: Option<u32>) -> &mut Self

Set the size of a page in the ThetaDB.

By default, it is the operating system’s memory page size. And the minimum page size is 4 KB.

pub fn force_sync(&mut self, flag: bool) -> &mut Self

Decide whether to force synchronization on every commit of the read write transaction.

If it is true, every commit of the read write transaction will be immediately followed by a sync operation. If it is false, sync operation will be performed according to the operating system’s internal logic.

pub fn mempool_capacity(&mut self, capacity: usize) -> &mut Self

Set the capacity of the memory pool. Represents the number of pages that can be reused.

By default, it is 4.

pub fn open(&self, path: impl AsRef<Path>) -> Result<ThetaDB>

Open a ThetaDB instance with the current options.
