Struct ServiceManifest 

pub struct ServiceManifest {
    pub name: String,
    pub version: Option<String>,
    pub tables: Vec<TableDefinition>,
    pub cells: Vec<CellDefinition>,
    pub events: Vec<EventDefinition>,
    pub subscriptions: Vec<SubscriptionDefinition>,
    pub custom_routes: Vec<CustomRouteDefinition>,
    pub mode: ServiceMode,
    pub authorization: Option<AuthorizationConfig>,
    pub on_migrate: Option<String>,
}

A service manifest describes the complete definition of a cufflink service. This is generated by the SDK macros from the user’s Rust struct definitions.

Fields

name: String

version: Option<String>

tables: Vec<TableDefinition>

cells: Vec<CellDefinition>

events: Vec<EventDefinition>

subscriptions: Vec<SubscriptionDefinition>

custom_routes: Vec<CustomRouteDefinition>

mode: ServiceMode

authorization: Option<AuthorizationConfig>

Authorization configuration (permission areas and default roles).

on_migrate: Option<String>

Optional WASM handler invoked between additive and destructive schema phases of a deploy. Used to backfill or restructure data when columns are split, renamed, or have their semantics changed. The handler must be idempotent — it may be re-invoked on retried deploys.

Implementations

impl ServiceManifest

pub fn get_table(&self, name: &str) -> Option<&TableDefinition>

Get table definition by name

pub fn requires_wasm(&self) -> bool

Whether this manifest needs a WASM artifact bundled at deploy time.

A WASM module is required when the service runs user code: explicit mode: wasm, an on_migrate schema hook, table CRUD lifecycle hooks, or any Wasm subscription/custom-route handler. The CLI uses this to decide whether to compile a WASM artifact; the platform uses it to reject deploys that arrive without one.

pub fn declared_wasm_handlers(&self) -> Vec<&str>

All handler names this manifest expects the WASM module to export. Used at deploy time to reject manifests whose declared handlers are missing from the bundled binary.

pub fn schema_hash(&self) -> String

Compute a SHA-256 hash of the manifest for change detection
