Trait IterateIntoCache

pub trait IterateIntoCache: Iterator
where
    Self::Item: Clone,
{
    // Required methods
    fn cache(
        self,
        quantity: u32,
    ) -> Result<IteratorCache<Self::Item>, Box<dyn Error>>;
    fn cache_all(self) -> IteratorCache<Self::Item> ;
    fn cache_or_all(self, quantity: u32) -> IteratorCache<Self::Item> ;
}

Any Iterator can have its values cached with the methods in this trait. (Currently only iterators where Item: Clone are supported, due to trait bounds on the queue from the queues crate)

Required Methods

fn cache( self, quantity: u32, ) -> Result<IteratorCache<Self::Item>, Box<dyn Error>>

Cache a given amount of items from this iterator for use later.

Errors

Errors if the iterator runs out of items while caching To avoid the error, consider using cache_or_all()

fn cache_all(self) -> IteratorCache<Self::Item>

Cache all items from this iterator for use later

fn cache_or_all(self, quantity: u32) -> IteratorCache<Self::Item>

Cache a given amount of items from this iterator for use later, or end early if the iterator runs out
