Struct fuel_indexer::Database

impl Database

pub async fn new( pool: IndexerConnectionPool, manifest: &Manifest, config: &IndexerConfig ) -> Database

Create a new Database.

pub async fn start_transaction(&mut self) -> IndexerResult<usize>

Open a database transaction.

pub async fn commit_transaction(&mut self) -> IndexerResult<usize>

Commit transaction to database.

pub async fn revert_transaction(&mut self) -> IndexerResult<usize>

Revert open transaction.

pub async fn put_object( &mut self, type_id: i64, columns: Vec<FtColumn>, bytes: Vec<u8> ) -> IndexerResult<()>

Put an object into the database.

pub async fn get_object( &mut self, type_id: i64, object_id: String ) -> IndexerResult<Option<Vec<u8>>>

Get an object from the database.

pub async fn find_many( &mut self, type_id: i64, constraints: String ) -> IndexerResult<Vec<Vec<u8>>>

Get multiple objects from the database that satisfy the given constraints.

pub async fn load_schema(&mut self, version: String) -> IndexerResult<()>

Load the schema for this indexer from the database, and build a mapping of TypeIds to tables.

pub async fn put_many_to_many_record( &mut self, queries: Vec<String> ) -> IndexerResult<()>

Put a record into the database.

Specifically for many-to-many relationships.

Since many-to-many relationships can only ever reference certain ID fields on TypeDefinitions, we don’t need to save any FtColumn::Object columns, which means we can simplify the INSERT into a simple string.

There are multiple queries here because a single parent TypeDefinition can have several many-to-many relationships with children TypeDefinitions.
