Struct BTreeHandleStore 

pub struct BTreeHandleStore { /* private fields */ }

In-memory HandleStore keyed by HandleId with a reverse value index; the kernel default.

Implementations

impl BTreeHandleStore

pub fn new() -> Self

Creates an empty store.

pub fn len(&self) -> usize

Returns the number of interned values.

pub fn is_empty(&self) -> bool

Returns whether the store holds no values.

Trait Implementations

impl Clone for BTreeHandleStore

fn clone(&self) -> BTreeHandleStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BTreeHandleStore

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

Formats the value using the given formatter.

impl Default for BTreeHandleStore

fn default() -> BTreeHandleStore

Returns the “default value” for a type.

impl HandleStore for BTreeHandleStore

fn intern(&mut self, value: Value) -> HandleId

Interns value, returning its handle; equal values reuse one handle.

fn get(&self, id: &HandleId) -> Option<&Value>

Resolves the value for id, or None when it is not stored here.

fn contains(&self, id: &HandleId) -> bool

Returns whether id is interned in this store.

fn handle_for_value(&self, value: &Value) -> Option<HandleId>

Returns the existing handle for value, if one is interned.
