Struct timely::container::flatcontainer::impls::deduplicate::CollapseSequence

pub struct CollapseSequence<R>
where
    R: Region,
{ /* private fields */ }

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::{Push, StringRegion};
let mut r = <CollapseSequence<StringRegion>>::default();

assert_eq!(r.push("abc"), r.push("abc"));

Trait Implementations

impl<R> Clone for CollapseSequence<R>

where R: Region + Clone,

fn clone(&self) -> CollapseSequence<R>

Returns a copy of the value.

fn clone_from(&mut self, source: &CollapseSequence<R>)

Performs copy-assignment from source.

impl<R> Debug for CollapseSequence<R>

where R: Debug + Region, <R as Region>::Index: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<R> Default for CollapseSequence<R>

where R: Region,

fn default() -> CollapseSequence<R>

Returns the “default value” for a type.

impl<'de, R> Deserialize<'de> for CollapseSequence<R>

where R: Region + Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D, ) -> Result<CollapseSequence<R>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<R, T> Push<T> for CollapseSequence<R>

where R: Region + Push<T>, T: for<'a> PartialEq<<R as Region>::ReadItem<'a>>,

fn push(&mut self, item: T) -> <CollapseSequence<R> as Region>::Index

Push item into self, returning an index that allows to look up the corresponding read item.

impl<R> Region for CollapseSequence<R>

where R: Region,

type Owned = <R as Region>::Owned

An owned type that can be constructed from a read item.

type ReadItem<'a> = <R as Region>::ReadItem<'a> where CollapseSequence<R>: 'a

The type of the data that one gets out of the container.

type Index = <R as Region>::Index

The type to index into the container. Should be treated as an opaque type, even if known.

fn merge_regions<'a>( regions: impl Iterator<Item = &'a CollapseSequence<R>> + Clone, ) -> CollapseSequence<R>

where CollapseSequence<R>: 'a,

Construct a region that can absorb the contents of regions in the future.

fn index( &self, index: <CollapseSequence<R> as Region>::Index, ) -> <CollapseSequence<R> as Region>::ReadItem<'_>

Index into the container. The index must be obtained by pushing data into the container.

fn reserve_regions<'a, I>(&mut self, regions: I)

where CollapseSequence<R>: 'a, I: Iterator<Item = &'a CollapseSequence<R>> + Clone,

Ensure that the region can absorb the items of regions without reallocation

fn clear(&mut self)

Remove all elements from this region, but retain allocations if possible.

fn heap_size<F>(&self, callback: F)

where F: FnMut(usize, usize),

Heap size, size - capacity

fn reborrow<'b, 'a>( item: <CollapseSequence<R> as Region>::ReadItem<'a>, ) -> <CollapseSequence<R> as Region>::ReadItem<'b>

where 'a: 'b, CollapseSequence<R>: 'a,

Converts a read item into one with a narrower lifetime.

impl<R> Serialize for CollapseSequence<R>

where R: Region + Serialize,

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
