Trait basic_dsp_vector::MapAggregateOps

pub trait MapAggregateOps<T, R>: Sized where
    T: Sized,
    R: Send, {
    type Output;
    fn map_aggregate<'a, A, FMap, FAggr>(
        &self, 
        argument: A, 
        map: &FMap, 
        aggregate: &FAggr
    ) -> Self::Output
    where
        A: Sync + Copy + Send,
        FMap: Fn(T, usize, A) -> R + 'a + Sync,
        FAggr: Fn(R, R) -> R + 'a + Sync + Send;
}

Operations which allow to iterate over the vector and to derive results.

Required methods

fn map_aggregate<'a, A, FMap, FAggr>(
    &self,
    argument: A,
    map: &FMap,
    aggregate: &FAggr
) -> Self::Output where
    A: Sync + Copy + Send,
    FMap: Fn(T, usize, A) -> R + 'a + Sync,
    FAggr: Fn(R, R) -> R + 'a + Sync + Send, 

Transforms all vector elements using the function map and then aggregates all the results with aggregate. aggregate must be a commutativity and associativity; that’s because there is no guarantee that the numbers will be aggregated in any deterministic order.
