Implementations§

Source§

impl<R: Runtime> Persistence<R>

Source

pub async fn open_context( &self, name: impl AsRef<str>, path: impl AsRef<str>, ) -> Result<Context<R>>

Opens a context at a path, or returns the existing context if it’s already open at that path. Attmepting to open an existing context at a new path will fail.

Source

pub async fn aliased_context(&self, name: impl AsRef<str>) -> Result<Context<R>>

Returns an already-open context

Source

pub async fn context(&self, context: ContextSpecifier) -> Result<Context<R>>

Returns a context based on a ContextSpecifier. This abstracts Persistence::open_context and Persistence::aliased_context

Source

pub async fn database( &self, context: ContextSpecifier, database: DatabaseSpecifier, ) -> Result<Database<R>>

Returns a database based on a ContextSpecifier and a DatabaseSpecifier

Source

pub async fn file_handle( &self, context: ContextSpecifier, file_handle: FileHandleSpecifier, ) -> Result<FileHandle<R>>

Returns a file handle based on a ContextSpecifier and a FileHandleSpecifier

Source

pub async fn transaction( &self, context: ContextSpecifier, database: DatabaseSpecifier, transaction: Uuid, ) -> Result<Transaction<R>>

Returns an open transaction based on a ContextSpecifier and a DatabaseSpecifier, as well as the transaction ID

Source

pub async fn collection<T: Serialize + DeserializeOwned + Sync + Send>( &self, context: ContextSpecifier, database: DatabaseSpecifier, collection: CollectionSpecifier, ) -> Result<Collection<T, R>>

Returns a collection based on a ContextSpecifier, DatabaseSpecifier, and a CollectionSpecifier

Source

pub async fn close_context(&self, context: ContextSpecifier) -> Result<()>

Closes a context based on a ContextSpecifier

Source

pub async fn cleanup(&self) -> Result<()>

Closes all active contexts and removes them from tracking.
