Struct SchemaPlan 

pub struct SchemaPlan {
    pub pack: &'static str,
    pub statements: &'static [&'static str],
}

Pack-auxiliary schema plan.

Declares CREATE TABLE IF NOT EXISTS statements for pack-owned tables that are NOT part of the core substrate schema (entities, notes, edges, events). Applied at boot via StorageBackend::apply_schema / apply_pack_schema_plan.

Core substrate tables evolve through versioned migrations. Pack schema is strictly for pack-auxiliary tables (e.g. GTD lifecycle audit, memory index). v1 pack schemas are non-versioned.

Fields

pack: &'static str

Owning pack name.

statements: &'static [&'static str]

DDL statements applied idempotently at boot. Each entry must be a self-contained CREATE TABLE IF NOT EXISTS or similar idempotent statement.

Implementations

impl SchemaPlan

pub const fn empty() -> Self

Construct a SchemaPlan with no statements.

Packs whose state lives entirely in the core substrate tables (entities, notes, edges) use this as their schema_plan() return value.

pub fn is_empty(&self) -> bool

Returns true when the plan contains no DDL statements.

Trait Implementations

impl Clone for SchemaPlan

fn clone(&self) -> SchemaPlan

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SchemaPlan

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for SchemaPlan

fn default() -> SchemaPlan

Returns the “default value” for a type.
