Struct TenantId 

pub struct TenantId(pub u32);

Resolved tenant ordinal: the 4-byte prefix of every tenant-owned key . Assigned once by the tenant directory and never reused, so a purged tenant’s leftovers can never become visible to a later tenant.

Tuple Fields

0: u32

Implementations

impl TenantId

pub const SYSTEM: Self

Reserved for system rows; never assigned to a tenant.

pub const SINGLE: Self

The fixed tenant of single-tenant deployments.

pub const FIRST_ASSIGNED: u32 = 2

First ordinal the tenant directory assigns.

pub const UNREGISTERED: Self

A scope the directory has never registered. Never assigned, so it owns no keys: every read through it is empty.

pub fn single() -> Self

The fixed identity used by single-tenant deployments.

pub const fn from_ordinal(ordinal: u64) -> Self

A tenant id from an ordinal the caller already resolved (tests, embedders, and the directory itself).

Panics

Panics if ordinal does not fit the 4-byte key prefix.

pub const fn to_be_bytes(self) -> [u8; 4]

Big-endian key-prefix bytes.
