Trait Implementations

impl Entity for Tank

type PrimaryKey<'a> = (&'a String,)

Primary key type. A tuple of field types (or single type) forming the PK.

fn table() -> &'static TableRef

Table reference matching the #[tank(...)] attributes.

fn columns() -> &'static [ColumnDef]

All column definitions in declaration order.

fn primary_key_def() -> &'static [&'static ColumnDef]

Primary key column definitions. Empty if no PK defined.

fn primary_key<'a>(&'a self) -> Self::PrimaryKey<'a>

Extract PK value(s) from self.

fn primary_key_expr(&self) -> impl Expression

Build an expression matching the PK of self.

fn unique_defs() -> impl ExactSizeIterator<Item = impl ExactSizeIterator<Item = &'static ColumnDef>>

Unique constraint definitions.

fn row_filtered(&self) -> Box<[(&'static str, Value)]>

Column name-value pairs for persistence (excludes ignored/default fields).

fn row_full(&self) -> RowValues

Full row representation including all persisted columns.

fn from_row(row: Row) -> Result<Self>

Reconstruct Self from a labeled row.

fn row_labeled(&self) -> Row

Full row representation with column labels.

fn create_table( executor: &mut impl Executor, if_not_exists: bool, create_schema: bool, ) -> impl Future<Output = Result<(), Error>> + Send

where Self: Sized,

Create table (and optional schema).

fn drop_table( executor: &mut impl Executor, if_exists: bool, drop_schema: bool, ) -> impl Future<Output = Result<(), Error>> + Send

where Self: Sized,

Drop the table (and optional schema).

fn insert_one( executor: &mut impl Executor, entity: &impl Entity, ) -> impl Future<Output = Result<RowsAffected, Error>> + Send

Insert a single entity.

fn insert_many<'a, It>( executor: &mut impl Executor, items: It, ) -> impl Future<Output = Result<RowsAffected, Error>> + Send

where Self: Sized + 'a, It: IntoIterator<Item = &'a Self> + Send, <It as IntoIterator>::IntoIter: Send,

Bulk insert entities.

fn prepare_find<Exec>( executor: &mut Exec, condition: impl Expression, limit: Option<u32>, ) -> impl Future<Output = Result<Query<<Exec as Executor>::Driver>, Error>>

where Exec: Executor,

Prepare (but do not yet run) a SQL select query.

fn find_one( executor: &mut impl Executor, condition: impl Expression, ) -> impl Future<Output = Result<Option<Self>, Error>> + Send

where Self: Sized,

Finds the first entity matching a condition expression.

fn find_many( executor: &mut impl Executor, condition: impl Expression, limit: Option<u32>, ) -> impl Stream<Item = Result<Self, Error>> + Send

where Self: Sized,

Streams entities matching a condition.

fn delete_many( executor: &mut impl Executor, condition: impl Expression, ) -> impl Future<Output = Result<RowsAffected, Error>> + Send

where Self: Sized,

Deletes all entities matching a condition.

fn save( &self, executor: &mut impl Executor, ) -> impl Future<Output = Result<(), Error>> + Send

where Self: Sized,

Saves the entity (insert or update if available) based on primary key presence.

fn delete( &self, executor: &mut impl Executor, ) -> impl Future<Output = Result<(), Error>> + Send

where Self: Sized,

Deletes this entity instance via its primary key.
