Expand description

A trait describing a minimal, asynchronous repository interface for an entity T identified by key K. This is intentionally DB-agnostic. Concrete backends provide implementations.

Required Methods§

Source

fn find_by_id<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 <T as Identifiable>::Key, ) -> Pin<Box<dyn Future<Output = Result<Option<T>, RepoError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Fetch an entity by its primary key. Returns Ok(None) if not found.

Source

fn find_by_field<'life0, 'life1, 'async_trait>( &'life0 self, field_name: &'life1 str, value: ParamValue, ) -> Pin<Box<dyn Future<Output = Result<Vec<T>, RepoError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

A generic finder for a single field. Returns a (possibly empty) Vec of entities. This is the low-level hook used by macro-generated find_by_<field> methods.

Source

fn insert<'life0, 'life1, 'async_trait>( &'life0 self, entity: &'life1 T, ) -> Pin<Box<dyn Future<Output = Result<T, RepoError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Insert a new entity. The returned entity may be different if the database generates some fields (e.g., auto-incrementing IDs).

Source

fn update<'life0, 'life1, 'async_trait>( &'life0 self, entity: &'life1 T, ) -> Pin<Box<dyn Future<Output = Result<T, RepoError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Update an existing entity. The returned entity may be different if the database modifies it (e.g., ON UPDATE timestamps).

Source

fn delete_by_id<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 <T as Identifiable>::Key, ) -> Pin<Box<dyn Future<Output = Result<bool, RepoError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Delete an entity by key. Returns true if a row was affected.
