Struct CatalogGeneration 

pub struct CatalogGeneration(/* private fields */);

Monotonic catalog mutation counter. Every catalog mutation advances the generation so stale activations can be detected and invalidated.

Implementations

impl CatalogGeneration

pub const fn initial() -> Self

pub const fn new(value: u64) -> Self

Construct a generation at an explicit value (boundary tests, resuming persisted counters). Constructing a generation grants nothing.

pub fn checked_next(self) -> Result<Self, CatalogGenerationOverflow>

Fail-closed advancement: at u64::MAX there is no new generation, so the caller must abort its mutation instead of wrapping or sticking (either of which could let stale grants keep validating).

pub const fn value(self) -> u64
