Trait DataScopeExt 

pub trait DataScopeExt: Sized {
    // Required method
    fn with_data_scope_conditions(self, conditions: &[WhereCondition]) -> Self;

    // Provided method
    fn data_scope_async<'life0, 'life1, 'life2, 'async_trait>(
        self,
        ctx: &'life0 DataScopeContext,
        rule: &'life1 DataScopeRule,
        evaluator: &'life2 dyn DataScopeEvaluator,
    ) -> Pin<Box<dyn Future<Output = Result<Self, DataScopeError>> + Send + 'async_trait>>
       where Self: Send + 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait,
             'life2: 'async_trait { ... }
}

数据范围扩展 trait

为查询构建器实现此 trait 后，可链式调用 .data_scope_async(ctx, rule, evaluator) 自动注入数据范围 WHERE 条件。

Required Methods

fn with_data_scope_conditions(self, conditions: &[WhereCondition]) -> Self

同步设置数据范围（需预先评估好的条件）

Provided Methods

fn data_scope_async<'life0, 'life1, 'life2, 'async_trait>( self, ctx: &'life0 DataScopeContext, rule: &'life1 DataScopeRule, evaluator: &'life2 dyn DataScopeEvaluator, ) -> Pin<Box<dyn Future<Output = Result<Self, DataScopeError>> + Send + 'async_trait>>

where Self: Send + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

异步评估并注入数据范围

调用 evaluator.evaluate(ctx, rule) 获取条件列表， 逐个追加到查询构建器。

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
