Struct ClassCache 

pub struct ClassCache<M> { /* private fields */ }

A bounded managed class universe with non-retaining derived caches.

Implementations

impl<M: Clone> ClassCache<M>

pub fn new(max_objects: usize) -> Result<Self, CacheError>

Creates a cache with a hard cap shared by classes and derived values.

pub fn allocate_class( &mut self, parents: &[ClassRoot], members: Vec<M>, ) -> Result<ClassRoot, CacheError>

Allocates and roots a class with its declared parents and members.

pub fn replace_parents( &mut self, class: ClassRoot, parents: &[ClassRoot], ) -> Result<(), CacheError>

Replaces declared parents and bumps the parent revision.

pub fn replace_members( &mut self, class: ClassRoot, members: Vec<M>, ) -> Result<(), CacheError>

Replaces declared members and bumps the member revision.

pub fn derived<P>( &mut self, class: ClassRoot, policy: &P, budget: LineageBudget, ) -> Result<CacheAccess<M>, CacheError>

where P: LineagePolicy<SnapshotGraph<M>>,

Returns a revision-validated cached view or computes and installs one.

pub fn release(&mut self, class: ClassRoot) -> Result<(), CacheError>

Releases the caller’s strong root. Collection can then reclaim the class and cache value.

pub fn collect( &mut self, limits: CollectionLimits, ) -> Result<CollectionReceipt, CacheError>

Runs bounded MANAGED_2 tracing collection and returns its exact receipt.

pub fn managed_len(&self) -> usize

Returns the current number of managed manager, class, and derived objects.
