Struct PropertyStore 

pub struct PropertyStore<O, K, V, H> { /* private fields */ }

Ordered own-property records keyed by caller-owned object identities.

This store deliberately has no parent pointer and no built-in traversal or precedence rule. Callers supply an already-policy-ordered owner slice for every inherited operation.

Implementations

impl<O, K, V, H> PropertyStore<O, K, V, H>

pub const fn new() -> Self

Creates an empty property store without imposing Default on its caller-owned identity, key, value, or hook types.

impl<O, K, V, H> PropertyStore<O, K, V, H>

where O: Clone + Eq + Hash, K: Clone + Eq + Hash, V: Clone + PartialEq, H: Clone + PartialEq,

pub fn own(&self, owner: &O, key: &K) -> Option<&Descriptor<V, H>>

Returns an own descriptor without invoking it.

pub fn define( &mut self, owner: &O, key: K, descriptor: Descriptor<V, H>, ) -> Result<(), DefineError>

Defines an own property, retaining its original key position on update.

pub fn delete(&mut self, owner: &O, key: &K) -> Result<bool, DefineError>

Deletes an own property. Missing properties succeed.

pub fn own_keys(&self, owner: &O, enumerable_only: bool) -> Vec<K>

Returns own keys in stable definition order, optionally filtering out non-enumerable records. Delete followed by define appends a fresh key.

pub fn get<E>( &self, owners: &[O], receiver: &O, key: &K, context: &mut AccessContext<O, K>, hooks: &mut impl PropertyHook<O, K, V, H, Error = E>, ) -> Result<Option<V>, AccessError<E>>

Reads along an explicitly supplied owner order. Duplicate owners are skipped, making cyclic caller-produced orders safe.

pub fn set<E>( &mut self, owners: &[O], receiver: &O, key: &K, value: V, context: &mut AccessContext<O, K>, hooks: &mut impl PropertyHook<O, K, V, H, Error = E>, ) -> Result<bool, AccessError<E>>

Assigns through the first descriptor in an explicit owner order. Writable data is updated on its owner; accessor setters receive the original receiver. Missing and read-only properties return Ok(false).

Trait Implementations

impl<O: Clone, K: Clone, V: Clone, H: Clone> Clone for PropertyStore<O, K, V, H>

fn clone(&self) -> PropertyStore<O, K, V, H>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<O: Debug, K: Debug, V: Debug, H: Debug> Debug for PropertyStore<O, K, V, H>

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

Formats the value using the given formatter.

impl<O: Default, K: Default, V: Default, H: Default> Default for PropertyStore<O, K, V, H>

fn default() -> PropertyStore<O, K, V, H>

Returns the “default value” for a type.
