Struct Interner 

pub struct Interner<Id: Identifier, T> { /* private fields */ }

A generic append-only interner: an address-stable Registry behind an RwLock. Pushes take a write lock; reads (Index) take a read lock and hand back a stable &T.

Implementations

impl<Id: Identifier, T> Interner<Id, T>

pub fn push(&self, value: T) -> Id

Appends value, returning its stable id. Takes a write lock.

pub fn len(&self) -> usize

The number of interned values.

pub fn is_empty(&self) -> bool

Whether the interner is empty.

impl<Id: Identifier, T: Clone> Interner<Id, T>

pub fn iter(&self) -> impl Iterator<Item = Identified<Id, T>>

An owned snapshot of all (id, value) pairs in id order. Owned (cloned) so it does not borrow through the lock; callers that only need ids or a stable &T should prefer indexing.

Trait Implementations

impl<Id: Identifier, T: Clone> Clone for Interner<Id, T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Id: Identifier, T> Default for Interner<Id, T>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, Id: Identifier, T: Deserialize<'de>> Deserialize<'de> for Interner<Id, T>

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl<Id: Identifier, T> Index<Id> for Interner<Id, T>

type Output = T

The returned type after indexing.

fn index(&self, id: Id) -> &T

Performs the indexing (container[index]) operation.

impl<Id: Identifier, T> IndexMut<Id> for Interner<Id, T>

fn index_mut(&mut self, id: Id) -> &mut T

Performs the mutable indexing (container[index]) operation.

impl<Id: Identifier, T: Serialize> Serialize for Interner<Id, T>

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
