Struct SchemaDomain 

pub struct SchemaDomain {
    pub name: &'static str,
    pub migrations: &'static [Migration],
    pub initialize_current: fn(&Transaction<'_>) -> Result<(), Error>,
    pub allowed_existing_versions: &'static [i64],
    pub released_predecessors: &'static [SchemaPredecessor],
    pub owned_objects: &'static [SchemaObject],
    pub retired_objects: &'static [SchemaObject],
}

A store’s schema domain: its ledger name plus the ordered migration list.

Fields

name: &'static str

Ledger key. Kebab-case, stable forever (it is persisted in files).

migrations: &'static [Migration]

Ordered migrations, versions contiguous from 1.

initialize_current: fn(&Transaction<'_>) -> Result<(), Error>

Initialize a genuinely fresh domain directly at the current schema.

This is intentionally separate from historical upgrades. A current base initializer may already contain objects that a released predecessor transition creates or rebuilds; replaying the transition on fresh state would either collide or weaken strict collision detection with idempotent DDL.

allowed_existing_versions: &'static [i64]

Exact existing released versions that this binary may open. The current supported version is included for an explicit manifest even though it needs no migration.

released_predecessors: &'static [SchemaPredecessor]

Exact catalog verifiers for every allowed version below current.

owned_objects: &'static [SchemaObject]

Complete set of catalog objects owned by this domain across its current schema. Foreign co-tenant objects are deliberately absent.

retired_objects: &'static [SchemaObject]

Names owned by supported predecessors but intentionally absent from the current schema. They remain reserved for fresh-domain detection and predecessor fingerprints.

Implementations

impl SchemaDomain

pub fn supported_version(&self) -> i64

Trait Implementations
