Trait Implementations

impl BookColumnTrait for Book

const isbn: ColumnRef

const title: ColumnRef

const author: ColumnRef

const co_author: ColumnRef

const year: ColumnRef

impl Clone for Book

fn clone(&self) -> Book

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Book

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

Formats the value using the given formatter.

impl Entity for Book

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

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_values(&self) -> RowValues

Full row representation including all persisted columns.

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

Reconstruct Self from a labeled row.

fn row(&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>> + Send

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.

impl Expression for Book

fn write_query( &self, writer: &dyn SqlWriter, context: &mut Context, out: &mut DynQuery, )

Generates the SQL representation of this expression.

fn accept_visitor( &self, _matcher: &mut dyn ExpressionVisitor, _writer: &dyn SqlWriter, _context: &mut Context, _out: &mut DynQuery, ) -> bool

Traverses the expression with a visitor.

fn as_identifier(&self, context: &mut Context) -> String

Renders the expression as a string suitable for use as an identifier.

impl OpPrecedence for Book

fn precedence(&self, _: &dyn SqlWriter) -> i32

Lower numbers bind weaker, writers parenthesize when child precedence <= operator precedence.

impl PartialEq for Book

fn eq(&self, other: &Book) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
