Struct Database 

pub struct Database { /* private fields */ }

The process-wide managed database capability.

Implementations

impl Database

pub async fn connect(config: DatabaseConfig, observer: Observer) -> Result<Self>

Creates the single managed pool and verifies that it can connect.

pub async fn query_all( &self, parent: &CallContext, statement: Statement, ) -> Result<Vec<DbRow>>

pub async fn query_optional( &self, parent: &CallContext, statement: Statement, ) -> Result<Option<DbRow>>

pub async fn write( &self, parent: &CallContext, statement: Statement, ) -> Result<WriteResult>

pub async fn transaction<T, F>( &self, parent: &CallContext, operation: impl Into<OperationId>, work: F, ) -> Result<T>

where T: Send, F: for<'a> FnOnce(&'a mut Transaction) -> TransactionFuture<'a, T> + Send,

Runs one explicit, single-level transaction.

The callback returns a boxed async block because that is the minimal Rust API that safely ties all operations to the borrowed transaction.
