A Trait for a Model

Required Associated Types

type Entity: EntityTrait

Required Methods

fn get(&self, c: <Self::Entity as EntityTrait>::Column) -> Value

Get the Value of a column from an Entity

fn set(&mut self, c: <Self::Entity as EntityTrait>::Column, v: Value)

Set the Value of a column in an Entity

Provided Methods

fn find_related<R>(&self, _: R) -> Select<R>

where R: EntityTrait, Self::Entity: Related<R>,

Find related Models

fn find_linked<L>(&self, l: L) -> Select<L::ToEntity>

where L: Linked<FromEntity = Self::Entity>,

Find linked Models

fn delete<'a, 'async_trait, A, C>( self, db: &'a C, ) -> Pin<Box<dyn Future<Output = Result<DeleteResult, DbErr>> + Send + 'async_trait>>

where Self: IntoActiveModel<A> + 'async_trait, C: ConnectionTrait + 'async_trait, A: ActiveModelTrait<Entity = Self::Entity> + ActiveModelBehavior + Send + 'a + 'async_trait, 'a: 'async_trait,

Delete a model

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
