Enum sea_orm::entity::prelude::DatabaseConnection

pub enum DatabaseConnection {
    SqlxMySqlPoolConnection(SqlxMySqlPoolConnection),
    SqlxPostgresPoolConnection(SqlxPostgresPoolConnection),
    SqlxSqlitePoolConnection(SqlxSqlitePoolConnection),
    MockDatabaseConnection(Arc<MockDatabaseConnection>),
    Disconnected,
}

Handle a database connection depending on the backend enabled by the feature flags. This creates a database pool.

Variants

The connection to the database has been severed

Implementations

impl DatabaseConnection

pub fn as_mock_connection(&self) -> &MockDatabaseConnection

This is supported on crate feature mock only.

Generate a database connection for testing the Mock database

pub fn into_transaction_log(self) -> Vec<Transaction>

This is supported on crate feature mock only.

Get the transaction log as a collection Vec<crate::Transaction>

Trait Implementations

impl<'a> ConnectionTrait<'a> for DatabaseConnection

fn transaction<'life0, 'async_trait, F, T, E>(
    &'life0 self,
    _callback: F
) -> Pin<Box<dyn Future<Output = Result<T, TransactionError<E>>> + Send + 'async_trait>> where
    F: for<'c> FnOnce(&'c DatabaseTransaction) -> Pin<Box<dyn Future<Output = Result<T, E>> + Send + 'c>> + Send,
    T: Send,
    E: Error + Send,
    F: 'async_trait,
    T: 'async_trait,
    E: 'async_trait,
    'life0: 'async_trait,
    Self: 'async_trait, 

Execute the function inside a transaction. If the function returns an error, the transaction will be rolled back. If it does not return an error, the transaction will be committed.

type Stream = QueryStream

Create a stream for the QueryResult

fn get_database_backend(&self) -> DbBackend

Fetch the database backend as specified in DbBackend. This depends on feature flags enabled.

fn execute<'life0, 'async_trait>(
    &'life0 self,
    stmt: Statement
) -> Pin<Box<dyn Future<Output = Result<ExecResult, DbErr>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Execute a Statement

fn query_one<'life0, 'async_trait>(
    &'life0 self,
    stmt: Statement
) -> Pin<Box<dyn Future<Output = Result<Option<QueryResult>, DbErr>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Execute a Statement and return a query

fn query_all<'life0, 'async_trait>(
    &'life0 self,
    stmt: Statement
) -> Pin<Box<dyn Future<Output = Result<Vec<QueryResult>, DbErr>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Execute a Statement and return a collection Vec<QueryResult> on success

fn stream(
    &'a self,
    stmt: Statement
) -> Pin<Box<dyn Future<Output = Result<Self::Stream, DbErr>> + 'a>>

Execute a Statement and return a stream of results

fn begin<'life0, 'async_trait>(
    &'life0 self
) -> Pin<Box<dyn Future<Output = Result<DatabaseTransaction, DbErr>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Execute SQL BEGIN transaction. Returns a Transaction that can be committed or rolled back

fn is_mock_connection(&self) -> bool

Check if the connection is a test connection for the Mock database

impl Debug for DatabaseConnection

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DatabaseConnection

fn default() -> Self

Returns the “default value” for a type.
