Expand description

The low-level interface to a database’s schema::Schema, giving access to Collections and Viewss. This trait is for use within async contexts. For access outside of async contexts, use LowLevelConnection.

This trait’s methods are not designed for ergonomics. See AsyncConnection for a higher-level interface.

Required Methods§

source

fn apply_transaction<'life0, 'async_trait>( &'life0 self, transaction: Transaction ) -> Pin<Box<dyn Future<Output = Result<Vec<OperationResult>, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Applies a Transaction to the Schema. If any operation in the Transaction fails, none of the operations will be applied to the Schema.

source

fn get_from_collection<'life0, 'life1, 'async_trait>( &'life0 self, id: DocumentId, collection: &'life1 CollectionName ) -> Pin<Box<dyn Future<Output = Result<Option<OwnedDocument>, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Retrieves the document with id stored within the named collection.

This is a lower-level API. For better ergonomics, consider using one of:

source

fn get_multiple_from_collection<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ids: &'life1 [DocumentId], collection: &'life2 CollectionName ) -> Pin<Box<dyn Future<Output = Result<Vec<OwnedDocument>, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Retrieves all documents matching ids from the named collection. Documents that are not found are not returned, but no error will be generated.

This is a lower-level API. For better ergonomics, consider using one of:

source

fn list_from_collection<'life0, 'life1, 'async_trait>( &'life0 self, ids: Range<DocumentId>, order: Sort, limit: Option<u32>, collection: &'life1 CollectionName ) -> Pin<Box<dyn Future<Output = Result<Vec<OwnedDocument>, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Retrieves all documents within the range of ids from the named collection. To retrieve all documents, pass in .. for ids.

This is a lower-level API. For better ergonomics, consider using one of:

source

fn list_headers_from_collection<'life0, 'life1, 'async_trait>( &'life0 self, ids: Range<DocumentId>, order: Sort, limit: Option<u32>, collection: &'life1 CollectionName ) -> Pin<Box<dyn Future<Output = Result<Vec<Header>, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Retrieves all headers within the range of ids from the named collection. To retrieve all documents, pass in .. for ids.

This is a lower-level API. For better ergonomics, consider using one of:

source

fn count_from_collection<'life0, 'life1, 'async_trait>( &'life0 self, ids: Range<DocumentId>, collection: &'life1 CollectionName ) -> Pin<Box<dyn Future<Output = Result<u64, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Counts the number of documents within the range of ids from the named collection.

This is a lower-level API. For better ergonomics, consider using one of:

source

fn compact_collection_by_name<'life0, 'async_trait>( &'life0 self, collection: CollectionName ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Compacts the collection to reclaim unused disk space.

This process is done by writing data to a new file and swapping the file once the process completes. This ensures that if a hardware failure, power outage, or crash occurs that the original collection data is left untouched.

Errors

Error::CollectionNotFound: database name does not exist.
Error::Other: an error occurred while compacting the database.

source

fn query_by_name<'life0, 'life1, 'async_trait>( &'life0 self, view: &'life1 ViewName, key: Option<SerializedQueryKey>, order: Sort, limit: Option<u32>, access_policy: AccessPolicy ) -> Pin<Box<dyn Future<Output = Result<Vec<Serialized>, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Queries for view entries from the named view.

This is the lower-level API. For better ergonomics, consider querying the view using View::entries(self).query() instead. The parameters for the query can be customized on the builder returned from AsyncConnection::view().

source

fn query_by_name_with_docs<'life0, 'life1, 'async_trait>( &'life0 self, view: &'life1 ViewName, key: Option<SerializedQueryKey>, order: Sort, limit: Option<u32>, access_policy: AccessPolicy ) -> Pin<Box<dyn Future<Output = Result<MappedSerializedDocuments, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Queries for view entries from the named view with their source documents.

This is the lower-level API. For better ergonomics, consider querying the view using View::entries(self).query_with_docs() instead. The parameters for the query can be customized on the builder returned from AsyncConnection::view().

source

fn reduce_by_name<'life0, 'life1, 'async_trait>( &'life0 self, view: &'life1 ViewName, key: Option<SerializedQueryKey>, access_policy: AccessPolicy ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Reduces the view entries from the named view.

This is the lower-level API. For better ergonomics, consider querying the view using View::entries(self).reduce() instead. The parameters for the query can be customized on the builder returned from AsyncConnection::view().

source

fn reduce_grouped_by_name<'life0, 'life1, 'async_trait>( &'life0 self, view: &'life1 ViewName, key: Option<SerializedQueryKey>, access_policy: AccessPolicy ) -> Pin<Box<dyn Future<Output = Result<Vec<MappedSerializedValue>, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Reduces the view entries from the named view, reducing the values by each unique key.

This is the lower-level API. For better ergonomics, consider querying the view using View::entries(self).reduce_grouped() instead. The parameters for the query can be customized on the builder returned from AsyncConnection::view().

source

fn delete_docs_by_name<'life0, 'life1, 'async_trait>( &'life0 self, view: &'life1 ViewName, key: Option<SerializedQueryKey>, access_policy: AccessPolicy ) -> Pin<Box<dyn Future<Output = Result<u64, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Deletes all source documents for entries that match within the named view.

This is the lower-level API. For better ergonomics, consider querying the view using View::entries(self).delete_docs() instead. The parameters for the query can be customized on the builder returned from AsyncConnection::view().
