Struct PolymorphicJoinedSelect3 

pub struct PolymorphicJoinedSelect3<Base: Model, C1: Model, C2: Model, C3: Model> { /* private fields */ }

A polymorphic SELECT for joined-table inheritance base + three children.

Construct via select!(Base).polymorphic_joined3::<C1, C2, C3>().

Implementations

impl<Base: Model, C1: Model, C2: Model, C3: Model> PolymorphicJoinedSelect3<Base, C1, C2, C3>

pub fn filter(self, expr: Expr) -> Self

pub fn limit(self, n: u64) -> Self

Set LIMIT (delegates to the underlying base select).

pub fn offset(self, n: u64) -> Self

Set OFFSET (delegates to the underlying base select).

pub fn build_with_dialect(&self, dialect: Dialect) -> (String, Vec<Value>)

Build the SQL query and parameters.

pub async fn all<C: Connection>( self, cx: &Cx, conn: &C, ) -> Outcome<Vec<PolymorphicJoined3<Base, C1, C2, C3>>, Error>

Execute the polymorphic query and hydrate either Base or one of the three child types.
