Struct GlobalPosition 

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

Where a sealed record sits in the order every stream shares.

Positions start at 1 and strictly increase across all streams in the order the store accepted the appends; the store assigns them inside the transaction that lands the records, so two appends can never claim the same one. A consumer that reads every stream — a publisher, a projection — keeps a position as its cursor instead of one sequence per ceremony.

Implementations

impl GlobalPosition

pub const FIRST: Self

The position of the first record ever appended.

pub fn new(value: u64) -> Result<Self, DomainError>

pub fn value(self) -> u64

pub fn next(self) -> Self

The position the next record will take. Saturates rather than wrapping: a wrapped position would let a cursor replay the beginning.
