Struct Database

pub struct Database<'a> { /* private fields */ }

The database instance. Allows you to create rw_transaction and r_transaction, watch queries, and unwatch etc.

Example

use native_db::*;

fn main() -> Result<(), db_type::Error> {
   let builder = DatabaseBuilder::new();
   // Define models ...
   let db = builder.create_in_memory()?;
   // Open transactions
   // Watch data
   // Create snapshots
   // etc...
   Ok(())
}

Implementations

impl Database<'_>

pub fn rw_transaction(&self) -> Result<RwTransaction<'_>>

Creates a new read-write transaction.

pub fn r_transaction(&self) -> Result<RTransaction<'_>>

Creates a new read-only transaction.

impl Database<'_>

pub fn watch(&self) -> Watch<'_>

Watch queries.

pub fn unwatch(&self, id: u64) -> Result<()>

Unwatch the given id. You can get the id from the return value of watch. If the id is not valid anymore, this function will do nothing. If the id is valid, the corresponding watcher will be removed.

impl<'a> Database<'a>

pub fn redb_stats(&self) -> Result<Stats>

impl Database<'_>

pub fn snapshot<'a>( &self, builder: &'a DatabaseBuilder, path: &Path, ) -> Result<Database<'a>>
