Trait hotshot_types::traits::auction_results_provider::AuctionResultsProvider

pub trait AuctionResultsProvider<TYPES: NodeType>:
    Send
    + Sync
    + Clone {
    // Required method
    fn fetch_auction_result<'life0, 'async_trait>(
        &'life0 self,
        view_number: TYPES::View,
    ) -> Pin<Box<dyn Future<Output = Result<TYPES::AuctionResult>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

The AuctionResultsProvider trait is the sole source of Solver-originated state and interaction, and returns the results of the Solver’s allocation via the associated type. The associated type, AuctionResult, also implements the HasUrls trait, which requires that the output type has the requisite fields available.

Required Methods

fn fetch_auction_result<'life0, 'async_trait>( &'life0 self, view_number: TYPES::View, ) -> Pin<Box<dyn Future<Output = Result<TYPES::AuctionResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Fetches the auction result for a view. Does not cache the result, subsequent calls will invoke additional wasted calls.

Object Safety

This trait is not object safe.
