Struct DualArrayStore 

pub struct DualArrayStore {
    pub global: ArrayStore,
    pub local: ArrayStore,
}

Dual-arena array store with separate global and local backing stores.

Fields

global: ArrayStore

local: ArrayStore

Implementations

impl DualArrayStore

pub fn new() -> Self

pub fn allocated_objects(&self) -> usize

Combined high-water mark of both arenas, in object slots. See ArrayStore::allocated_objects.

pub fn allocate_at_level_zero(&mut self, len: usize) -> EntityId

Allocate len null-filled slots in local VM, stamped as if no save were outstanding.

The entity is stamped save_level = 0, global = false, created_after_save = 0 — it claims to predate every outstanding save. That is only true during bootstrap, before any save can have happened. Everywhere else prefer the VM-aware helpers in stet_ops::vm_ops (alloc_dict / alloc_array / alloc_string, or their _in variants): an entity mis-stamped this way is invisible to the invalidrestore check while still being released by the matching restore.

pub fn allocate_from_at_level_zero(&mut self, items: &[PsObject]) -> EntityId

Allocate and copy items into local VM, stamped as if no save were outstanding.

The entity is stamped save_level = 0, global = false, created_after_save = 0 — it claims to predate every outstanding save. That is only true during bootstrap, before any save can have happened. Everywhere else prefer the VM-aware helpers in stet_ops::vm_ops (alloc_dict / alloc_array / alloc_string, or their _in variants): an entity mis-stamped this way is invisible to the invalidrestore check while still being released by the matching restore.

pub fn allocate_from_with( &mut self, items: &[PsObject], save_level: u16, global: bool, created_after_save: u32, ) -> EntityId

Allocate and copy items with a specific save level and global flag.

pub fn allocate_with( &mut self, len: usize, save_level: u16, global: bool, created_after_save: u32, ) -> EntityId

Allocate with a specific save level and global flag.

pub fn get(&self, entity: EntityId, start: u32, len: u32) -> &[PsObject]

Get a slice of array elements.

pub fn get_mut( &mut self, entity: EntityId, start: u32, len: u32, ) -> &mut [PsObject]

Get a mutable slice of array elements.

pub fn get_element(&self, entity: EntityId, index: u32) -> PsObject

Get a single element.

pub fn set_element(&mut self, entity: EntityId, index: u32, obj: PsObject)

Set a single element.

pub fn cow_copy(&mut self, entity: EntityId) -> EntityId

COW copy (always local — global entities skip COW).

pub fn swap_offsets(&mut self, a: EntityId, b: EntityId)

Swap offsets between two entities (used by restore, always local).

pub fn entity_meta(&self, entity: EntityId) -> &EntityMeta

Get entity metadata (read-only).

pub fn entity_meta_mut(&mut self, entity: EntityId) -> &mut EntityMeta

Get mutable entity metadata.

pub fn entity_count(&self) -> usize

Total entity count across both stores.

pub fn reset_local(&mut self)

Reset local VM (for job boundary cleanup).
