Enum starfish::migrator::prelude::sea_orm::DatabaseConnection

pub enum DatabaseConnection {
    SqlxMySqlPoolConnection(SqlxMySqlPoolConnection),
    Disconnected,
}

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

Variants

SqlxMySqlPoolConnection(SqlxMySqlPoolConnection)

Create a MYSQL database connection and pool

Disconnected

The connection to the database has been severed

Implementations

impl DatabaseConnection

pub fn set_metric_callback<F>(&mut self, _callback: F) where
    F: 'static + Fn(&Info<'_>) + Send + Sync, 

Sets a callback to metric this connection

Trait Implementations

impl Clone for DatabaseConnection

fn clone(&self) -> DatabaseConnection

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ConnectionTrait for DatabaseConnection

fn get_database_backend(&self) -> DatabaseBackend

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, Global>> where
    'life0: 'async_trait,
    DatabaseConnection: '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, Global>> where
    'life0: 'async_trait,
    DatabaseConnection: '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, Global>, DbErr>> + Send + 'async_trait, Global>> where
    'life0: 'async_trait,
    DatabaseConnection: 'async_trait, 

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

fn support_returning(&self) -> bool

Check if the connection supports RETURNING syntax on insert and update

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<(), Error>

Formats the value using the given formatter.

impl Default for DatabaseConnection

fn default() -> DatabaseConnection

Returns the “default value” for a type.

impl<'a> StreamTrait<'a> for DatabaseConnection

type Stream = QueryStream

Create a stream for the QueryResult

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

Execute a Statement and return a stream of results

impl TransactionTrait 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, Global>> where
    'life0: 'async_trait,
    F: for<'c> FnOnce(&'c DatabaseTransaction) -> Pin<Box<dyn Future<Output = Result<T, E>> + Send + 'c, Global>> + Send + 'async_trait,
    T: Send + 'async_trait,
    E: Error + Send + 'async_trait,
    DatabaseConnection: '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.

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

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