Crate wowlab_buffer_contract 

Stable metadata and memory-layout contracts for the rotation engine.

Modules

field_offset

Pinned byte offsets for fields read by multi-field EvalKind variants.

Structs

FieldDescriptor

Inventory entry describing one expression-readable buffer field.

SlotDescriptor

Inventory entry describing one dense-buffer slot domain.

Enums

EvalKind

Operation used to interpret a field from the dense rotation buffer.

FieldType

Primitive value representation stored in a buffer field.

SlotKind

Whether a slot is a singleton or keyed by spell/aura/resource.

Constants

ACTION_ID_BITS 🔒

ACTION_ID_MASK

24-bit mask for the action ID field.

ACTION_ID_SHIFT

Shift for the 24-bit action ID at bits 32..56.

KIND_BITS 🔒

KIND_SHIFT

Shift for the high 8 kind bits in the packed [kind:8][action_id:24][payload:32] layout.

PACKED_BITS 🔒

PANDEMIC_REFRESH_FRACTION

Pandemic refresh fraction; an aura is refreshable once remaining < fraction * base_duration (WoW 30% window).

PAYLOAD_BITS 🔒

SLOT_ALIGNMENT

Required slot alignment, in bytes; assert_repr_c_layout rejects any field with a stricter alignment.

Functions

assert_repr_c_layout

Asserts that a repr(C) layout matches declared (size, alignment) pairs.

decode_eval_result

Decodes [kind:8][action_id:24][payload:32] into its components.

pack_eval_result

Packs an evaluation result into [kind:8][action_id:24][payload:32].
