Struct flatcontainer::impls::deduplicate::CollapseSequence
source · pub struct CollapseSequence<R: Region> { /* private fields */ }
Expand description
A region to deduplicate consecutive equal items.
§Examples
The following example shows that two inserts can result in the same index.
use flatcontainer::impls::deduplicate::CollapseSequence;
use flatcontainer::{CopyOnto, StringRegion};
let mut r = <CollapseSequence<StringRegion>>::default();
assert_eq!("abc".copy_onto(&mut r), "abc".copy_onto(&mut r));

§type ReadItem<'a> = <R as Region>::ReadItem<'a>

type ReadItem<'a> = <R as Region>::ReadItem<'a> where Self: 'a
The type of the data that one gets out of the container.
§type Index = <R as Region>::Index
type Index = <R as Region>::Index
The type to index into the container. Should be treated
as an opaque type, even if known.

fn index(&self, index: Self::Index) -> Self::ReadItem<'_>
Index into the container. The index must be obtained by
pushing data into the container.
