Struct foyer_common::async_batch_pipeline::LeaderToken

source · 
pub struct LeaderToken<T, R> { /* private fields */ }
Expand description

The token returns by AsyncBatchPipeline::accumulate if the caller is the leader of the batch.

Implementations§

source§

impl<T, R> LeaderToken<T, R>

source

pub fn pipeline<FR, F, FU, NS>( self, new_state: NS, fr: FR, f: F ) -> JoinHandle<()>
where T: Send + 'static, R: Send + 'static, FR: FnOnce(R) + Send + 'static, F: FnOnce(T) -> FU + Send + 'static, FU: Future<Output = R> + Send + 'static, NS: FnOnce(&T) -> T + Send + 'static,

Pipeline execute futures.

new_state

  • Receives the reference of the old state and returns the new state.

f

  • Receives the owned old state and returns a future.
  • The future will be polled after handling the previous result.
  • The future is guaranteed to be execute one by one in order.

fr

  • Handle the previous result.
