Trait ExtSortByExtension

pub trait ExtSortByExtension: Iterator {

Required Associated Types

type Run: Run<Self::Item>

Required Methods

fn external_sort_by<F>( self, options: ExtsortConfig, comparator: F, ) -> Result<LoserTree<Self::Item, ExternalRun<Self::Item, Box<dyn Read + Send>>, FuncOrderer<F>>>

where F: Fn(&Self::Item, &Self::Item) -> Ordering,

Sorts the provided Iterator according to the provided config using a custom comparator function

Errors

This function may error if a sort file fails to be written. In this case the library will do its best to clean up the already written files, but no guarantee is made.

fn external_sort_by_key<F, K>( self, options: ExtsortConfig, key_extractor: F, ) -> Result<LoserTree<Self::Item, ExternalRun<Self::Item, Box<dyn Read + Send>>, KeyOrderer<F>>>

where F: Fn(&Self::Item) -> K, K: Ord,

Sorts the provided Iterator according to the provided config using a key extraction function.

Errors

This function may error if a sort file fails to be written. In this case the library will do its best to clean up the already written files, but no guarantee is made.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
