The placement arithmetic and its data types live in nros-executor-layout (issue 1197) so a HOST build script can evaluate them for a target it is not compiling. Re-exported here because this is where every consumer already looks, and because NATIVE — the only part that names the types — has to live in the crate that owns them. Every element type the backing carves a table of, in declaration order.

The arena is absent on purpose: it is [MaybeUninit<u8>], size 1 align 1 by definition, and its LENGTH is a count rather than a unit.

Fields

callback_meta: RegionUnit

sched_context: RegionUnit

sched_context_id: RegionUnit

sporadic_state: RegionUnit

sporadic_atomic: RegionUnit

Placed only when Counts::alloc is set.

remap_rule: RegionUnit

node_record: RegionUnit

concrete_session: RegionUnit

extra_session_id: RegionUnit

node_sched_entry: RegionUnit

dispatch_slot: RegionUnit

component_slot: RegionUnit

group_name: RegionUnit

group_sched_entry: RegionUnit

violation: RegionUnit

alive_slot: RegionUnit

Alive supervision’s per-SchedContext record, one per sc.

slot_tag: RegionUnit

phase-476 W0 — the per-callback-slot lifetime tag (generation + owning node), one per cbs. Placed after every older region so each keeps its offset.

parameter_slot: RegionUnit

phase-382 W3’ — one parameter-store slot (nros_params::ParameterSlot), one per Counts::params. Placed LAST, for the reason slot_tag was: an image that carves no store (params == 0) keeps every offset and the total it had before the region existed.

param_home: RegionUnit

Issue 1812 — the parameter SERVICES’ home (nros_node’s ParamHome: their state, the shared request/reply buffer pair and the staging slot a remote set decodes its value into), one per Counts::param_home. Placed after the store’s slots for the same reason they are last: an image with no store keeps every offset and its total.
