Fields

name: &'static str

descriptor: SpaceDescriptor

vmrequest: VMRequest

copy: Option<CopySemantics>

For a copying space that allows sft_trace_object(), this should be set before each GC so we know

immortal: bool

movable: bool

contiguous: bool

zeroed: bool

permission_exec: bool

start: Address

extent: usize

vm_map: &'static dyn VMMap

mmapper: &'static dyn Mmapper

metadata: SideMetadataContext

needs_log_bit: bool

This field equals to needs_log_bit in the plan constraints.

acquire_lock: Mutex<()>

A lock used during acquire() to make sure only one thread can allocate.

gc_trigger: Arc<GCTrigger<VM>>

global_state: Arc<GlobalState>

options: Arc<Options>

p: PhantomData<VM>
