Function beagle::scalar_array::fold
[−]
[src]
pub fn fold<S, F0, F, O>(s: S, f0: F0, f: F) -> O where
S: ScalarArrayVal,
F0: FnOnce(S::Scalar) -> O,
F: FnMut(O, S::Scalar) -> O,
<S::Row as HasSmaller>::Smaller: Array<S::Scalar>,
<S::Dim as HasSmaller>::Smaller: Array<<S::Row as Array<S::Scalar>>::Type>,
Fold all the scalars in a ScalarArray
. The first element is mapped with f0
,
then folding continues with f
for other elements.
