A RegionInternal is a collection of Slots which are managed as a whole.

Required methods

fn new_instance_with(
    &self,
    module: Arc<dyn Module>,
    embed_ctx: CtxMap
) -> Result<InstanceHandle, Error>

fn drop_alloc(&self, alloc: &mut Alloc)

Unmaps the heap, stack, and globals of an Alloc, while retaining the virtual address ranges in its Slot.

fn expand_heap(&self, slot: &Slot, start: u32, len: u32) -> Result<(), Error>

Expand the heap for the given slot to include the given range.

fn reset_heap(
    &self,
    alloc: &mut Alloc,
