Trait Implementations

impl Clone for FakeDriver

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for FakeDriver

fn default() -> Self

Returns the “default value” for a type.

impl Driver for FakeDriver

fn dialect(&self) -> &dyn Dialect

fn query<'a>( &'a self, sql: &'a str, params: &'a [SqlValue], rows: &'a mut dyn RowSink, ) -> BoxFuture<'a, Result<()>>

fn transaction(&self, steps: Vec<Step>) -> BoxFuture<'_, Result<()>>

A unique-index refusal fails as Internal with a UniqueViolation source; a check, exclusion or foreign key as Rule (check_refusal, exclusion_refusal, …).

fn lock_migrations( &self, ) -> Option<Pin<Box<dyn Future<Output = Result<Box<dyn MigrationsLock>, Error>> + Send + '_>>>

Held over a whole Schema::migrate until dropped; else each migration’s transaction locks.

fn migrate_alone<'a>( &'a self, schema: &'a str, sql: &'a str, record: Step, ) -> Result<Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'a>>, Step>

Outside a transaction, under lock_migrations; other migrations get record back.

fn catalog(&self) -> Option<&dyn Catalog>

fn wakeups( &self, ) -> Option<Pin<Box<dyn Future<Output = Result<Box<dyn Wakeups>, Error>> + Send + '_>>>
