仓储 trait - 提供 CRUD 操作

Required Methods

async fn find_by_id(&self, id: E::Id) -> DatabaseResult<Option<E>>

根据主键查找

async fn find_all(&self) -> DatabaseResult<Vec<E>>

查找所有

async fn find_by(&self, condition: Condition) -> DatabaseResult<Vec<E>>

根据条件查找

async fn find_one(&self, condition: Condition) -> DatabaseResult<Option<E>>

根据条件查找一条

async fn insert(&self, entity: &E) -> DatabaseResult<i64>

where E: ToRow,

插入实体

async fn update(&self, entity: &E) -> DatabaseResult<u64>

where E: ToRow,

更新实体

async fn delete_by_id(&self, id: E::Id) -> DatabaseResult<u64>

根据主键删除

async fn delete_by(&self, condition: Condition) -> DatabaseResult<u64>

根据条件删除

async fn count(&self) -> DatabaseResult<u64>

统计数量

async fn count_by(&self, condition: Condition) -> DatabaseResult<u64>

根据条件统计

async fn exists(&self, id: E::Id) -> DatabaseResult<bool>

检查是否存在

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.
