}

A trait defining a hook for query execution.

Implementors of this trait can define custom logic to be executed at a specific stage of the query lifecycle. The trait provides a method to specify the stage at which the hook should be applied and another method to implement the hook’s logic.

Required Methods

fn stage(&self) -> HookStage

Returns the stage at which the hook should be applied.

Provided Methods

fn apply<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, ctx: &'life1 Query<T>, input: &'life2 mut HookInput<'life3, T>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Asynchronously applies the hook logic to a given query context and input.
