Function git_features::parallel::in_parallel[−][src]

pub fn in_parallel<I, S, O, R>(
    input: impl Iterator<Item = I> + Send, 
    thread_limit: Option<usize>, 
    new_thread_state: impl Fn(usize) -> S + Send + Sync, 
    consume: impl Fn(I, &mut S) -> O + Send + Sync, 
    reducer: R
) -> Result<<R as Reducer>::Output, <R as Reducer>::Error> where
    R: Reducer<Input = O>,
    I: Send,
    O: Send, 

Read items from input and consume them, producing an output to be collected by a reducer, whose task is to aggregate these outputs into the final result returned by this function.

  • if thread_limit is Some, the given amount of threads will be used. If None, all logical cores will be used.
  • new_thread_state(thread_number) -> State produces thread-local state once per thread to be based to consume
  • consume(Item, &mut State) -> Output produces an output given an input obtained by input along with mutable state initially created by new_thread_state(…).
  • For reducer, see the Reducer trait
