Struct ProjectionCheckpointOrdinal 

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

Coordinator-allocated nonzero checkpoint ordinal within one allocation incarnation.

Implementations

impl ProjectionCheckpointOrdinal

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

Reconstructs a nonzero ordinal; this does not grant allocation authority.

pub const fn first() -> Self

Initial position of a checked new-incarnation allocator.

pub const fn get(self) -> u64

Numeric ordinal, never a zero sentinel.

pub const fn to_be_bytes(self) -> [u8; 8]

Canonical ordered numeric representation.

pub const fn checked_next(self) -> Option<Self>

Checked successor; exhaustion never wraps or reuses an ordinal.
