Trait PickerSource

    + 'static {
    // Required methods
    fn search<'life0, 'life1, 'life2, 'async_trait>(
        &'life0 self,

    ) -> Pin<Box<dyn Future<Output = Result<Vec<PickerNode>, PickerError>> + Send + 'async_trait>>

        id: &'life2 str,
    ) -> Pin<Box<dyn Future<Output = Result<Option<PickerNode>, PickerError>> + Send + 'async_trait>>
       where Self: 'async_trait,

}

A source of picker candidates: a domain service the picker field and its endpoints call. Implementors build SQL in a scoped block and drop the builder before awaiting (sea-query identifiers are not Send), as the store queries elsewhere do.

Required Methods

fn search<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, db: &'life1 Db, q: &'life2 str, limit: u32, ) -> Pin<Box<dyn Future<Output = Result<Vec<PickerNode>, PickerError>> + Send + 'async_trait>>

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

Candidates matching q, capped at limit (the caller clamps it).

fn resolve<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, db: &'life1 Db, id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<Option<PickerNode>, PickerError>> + Send + 'async_trait>>

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

The node a stored id refers to, or None if it no longer exists.

Dyn Compatibility

This trait is dyn compatible.

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