Trait microkelvin::Nth

pub trait Nth<'a, A> where
    Self: Compound<A>,
    A: Annotation<Self::Leaf> + Borrow<Cardinality>, {
    fn nth(&'a self, n: u64) -> Result<Option<Branch<'a, Self, A>>, CanonError>;
    fn nth_mut(
        &'a mut self, 
        n: u64
    ) -> Result<Option<BranchMut<'a, Self, A>>, CanonError>
    where
        Self: MutableLeaves;
}

Trait that provides nth() and nth_mut() methods to any Compound with a Cardinality annotation

Required methods

fn nth(&'a self, n: u64) -> Result<Option<Branch<'a, Self, A>>, CanonError>

Construct a Branch pointing to the nth element, if any

fn nth_mut(
    &'a mut self,
    n: u64
) -> Result<Option<BranchMut<'a, Self, A>>, CanonError> where
    Self: MutableLeaves, 

Construct a BranchMut pointing to the nth element, if any
