Struct DualStringStore 

pub struct DualStringStore {
    pub global: StringStore,
    pub local: StringStore,
}

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

Fields

global: StringStore

local: StringStore

Implementations

impl DualStringStore

pub fn new() -> Self

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

Allocate len zero-filled bytes in local VM.

pub fn allocate_from(&mut self, bytes: &[u8]) -> EntityId

Allocate and copy bytes into local VM.

pub fn allocate_from_with( &mut self, bytes: &[u8], save_level: u16, global: bool, created_after_save: u32, ) -> EntityId

Allocate and copy bytes 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) -> &[u8]

Get a slice of the string data.

pub fn get_mut(&mut self, entity: EntityId, start: u32, len: u32) -> &mut [u8]

Get a mutable slice of the string data.

pub fn put_byte(&mut self, entity: EntityId, offset: u32, byte: u8)

Set a single byte.

pub fn get_byte(&self, entity: EntityId, offset: u32) -> u8

Get a single byte.

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 data(&self) -> &[u8]

Access local backing data (for vmstatus approximation).

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).

Trait Implementations

impl Default for DualStringStore

fn default() -> Self

Returns the “default value” for a type.
