    /* private fields */
}

Implementations

impl ArrayStore

pub fn new() -> Self

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

Allocate len null-filled slots, returning an EntityId.

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

Allocate and copy items into the store.

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 via entity table indirection.

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

Get a mutable slice of array elements via entity table indirection.

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

Copy entity data to a new region (for COW). Returns the new EntityId pointing at the backup. The original entity’s offset is updated to point at the fresh copy.

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

Swap offsets between two entities (used by restore).

Trait Implementations

impl Default for ArrayStore

fn default() -> Self

Returns the “default value” for a type.
