Enum PromotionState 

pub enum PromotionState {
    Observe,
    Shadow,
    NativeExperimental,
    NativeDefault,
    Fallback,
}

The promotion state of a subsystem (§3.2, §20).

Variants

Observe

Instrumented; observes and records only. Does not alter execution.

Shadow

Models behavior without changing the game’s result.

NativeExperimental

Native implementation active behind a feature flag; parity corpus required.

NativeDefault

Native implementation is the default path.

Fallback

A mature C implementation (Wine/vkd3d-proton/DXVK) is retained.

Implementations

impl PromotionState

pub const ALL: [PromotionState; 5]

All states in stable order (index = serialized index).

pub const fn as_str(self) -> &'static str

Stable string name.

pub const fn is_native(self) -> bool

Whether this state counts as “Katra native” for coverage reporting.

pub const fn is_fallback(self) -> bool

Whether this state counts as “legacy fallback” for coverage reporting.

pub const fn alters_execution(self) -> bool

Whether this state alters execution (vs. pure observation).
