Trait QueryEngine 

Source 
pub trait QueryEngine {
    // Required method
    fn select<'life0, 'life1, 'async_trait>(
        &'life0 self,
        filter: &'life1 Filter,
        today: Date,
    ) -> Pin<Box<dyn Future<Output = Vec<Id>> + 'async_trait>>

Expand description

Evaluate a query’s filter — the ids of tasks that match (unsorted). today is the reference date for due:today/overdue. Object-safe (no generic methods), so it rides in Services as &dyn. Sorting + breadcrumbs are the caller’s job (todoapp-app), identical across stores.

Required Methods§

Source

fn select<'life0, 'life1, 'async_trait>( &'life0 self, filter: &'life1 Filter, today: Date, ) -> Pin<Box<dyn Future<Output = Vec<Id>> + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Dyn Compatibility§

This trait is dyn compatible.

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