Implementations§

source§

impl ExternalSorter

source

pub fn sort<I, T>( &self, input: I, ) -> Result<impl ExactSizeIterator<Item = Result<T, ExternalChunkError>>, SortError>
where T: Serialize + DeserializeOwned + Send + Ord, I: IntoIterator<Item = T>,

Sorts data from the input. Returns an iterator that can be used to get sorted data stream.

§Arguments
  • input - Input stream data to be fetched from
source

pub fn sort_by<I, T, F>( &self, input: I, cmp: F, ) -> Result<impl ExactSizeIterator<Item = Result<T, ExternalChunkError>>, SortError>
where T: Serialize + DeserializeOwned + Send, I: IntoIterator<Item = T>, F: Fn(&T, &T) -> Ordering + Sync + Send + Copy,

Sorts a given iterator with a comparator function, returning a new iterator with items
