Struct shard_ecs::DefaultAllocator

pub struct DefaultAllocator;

Default allocator for components. Allocates in AoS fashion, storing components sequantially in memory.

Trait Implementations

impl<'s, C: Component> ComponentAllocator<'s, C> for DefaultAllocator

unsafe fn write_component_memory(pool_ptr: *mut u8, index: u16, src: *const u8)

Writes a component into the pool.

unsafe fn read_component_memory(pool_ptr: *const u8, index: u16, dst: *mut u8)

Reads a component from a pool.

unsafe fn drop_component_memory(pool_ptr: *mut u8, index: u16)

Calls the drop handler on the component at the given index.

unsafe fn move_component(
    source_pool: *const u8,
    src_index: u16,
    destination_pool: *mut u8,
    dst_index: u16
)

Moves a component from the source pool into the destination pool. Does not call drop.

unsafe fn get_component(pool_ptr: *const u8, index: u16) -> Self::RefType

Returns a reference to the component.

unsafe fn get_component_mut(pool_ptr: *mut u8, index: u16) -> Self::MutRefType

Returns a mutable reference to the component.

unsafe fn get_component_slice(
    pool_ptr: *const u8,
    len: usize
) -> Self::SliceType

Returns a slice to the components.

unsafe fn get_component_slice_mut(
    pool_ptr: *mut u8,
    len: usize
) -> Self::MutSliceType

Returns a mutable slice to the components.
