Enum Backend 

pub enum Backend {
    Sqlite(SqliteAdapter),
    Postgres(PostgresAdapter),
    PgBouncer(PgBouncerAdapter),
    Mysql(MySqlAdapter),
}

Cloning a backend is cheap: adapters share their connection pool.

Variants

Sqlite(SqliteAdapter)

Postgres(PostgresAdapter)

PgBouncer(PgBouncerAdapter)

Mysql(MySqlAdapter)

Implementations

impl Backend

pub async fn begin_transaction(&self) -> Result<TransactionExecutor>

pub fn sql_compiler(&self) -> &dyn DinocoSqlCompiler

The SQL compiler of this backend’s database.

pub fn set_logger(&mut self, enabled: bool)

pub fn logger_enabled(&self) -> bool

pub async fn query<M>(&self, query: FindQuery) -> Result<Vec<M>>

where M: DinocoRowModel,

pub async fn query_relation_join_optional<M>( &self, query: RelationJoinQuery, params: &[DinocoValue], ) -> Result<Vec<M>>

where M: DinocoRowModel,

pub async fn query_relation_batch<M>( &self, query: RelationBatchQuery, ) -> Result<Vec<M>>

where M: DinocoRowModel,

pub async fn query_many_to_many_relation<M>( &self, query: ManyToManyRelationQuery, params: &[DinocoValue], ) -> Result<Vec<M>>

where M: DinocoRowModel,

pub async fn insert(&self, query: InsertQuery) -> Result<usize>

pub async fn insert_returning<M>(&self, query: InsertQuery) -> Result<Vec<M>>

where M: DinocoRowModel,

pub async fn update(&self, query: UpdateQuery) -> Result<usize>

pub async fn update_returning<M>(&self, query: UpdateQuery) -> Result<Vec<M>>

where M: DinocoRowModel,

pub async fn atomic_update_returning<M>( &self, query: UpdateQuery, ) -> Result<Vec<M>>

where M: DinocoRowModel,

Executes the mutation before any MySQL compatibility read. This keeps arithmetic and WHERE predicates in one atomic UPDATE statement.

pub async fn delete(&self, query: DeleteQuery) -> Result<usize>

pub async fn delete_returning<M>(&self, query: DeleteQuery) -> Result<Vec<M>>

where M: DinocoRowModel,

pub async fn count(&self, query: CountQuery) -> Result<i64>

pub async fn exists(&self, query: ExistsQuery) -> Result<bool>

pub async fn find_batch(&self, query: FindBatchQuery) -> Result<Vec<Vec<Value>>>

pub async fn count_relation(&self, query: RelationCountQuery) -> Result<i64>

pub async fn count_many_to_many_relation( &self, query: ManyToManyRelationCountQuery, ) -> Result<i64>

Trait Implementations

impl Clone for Backend

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
