HostRuntime

Struct HostRuntime 

Source
pub struct HostRuntime { /* private fields */ }
Expand description

HostRuntime owns the lifecycle orchestration for ModKit.

It encapsulates all runtime state and drives modules through the full lifecycle (see module docs).

Implementations§

Source§

impl HostRuntime

Source

pub fn new( registry: ModuleRegistry, modules_cfg: Arc<dyn ConfigProvider>, db_options: DbOptions, client_hub: Arc<ClientHub>, cancel: CancellationToken, instance_id: Uuid, oop_options: Option<OopSpawnOptions>, ) -> Self

Create a new HostRuntime instance.

This prepares all runtime components but does not start any lifecycle phases.

Source

pub fn run_pre_init_phase(&self) -> Result<(), RegistryError>

PRE_INIT phase: wire runtime internals into system modules.

This phase runs before init and only for modules with the “system” capability.

§Errors

Returns RegistryError if system wiring fails.

Source

pub async fn run_module_phases(self) -> Result<()>

Run the full module lifecycle (all phases).

This is the standard entry point for normal application execution. It runs all phases from pre-init through shutdown.

§Errors

Returns an error if any module phase fails during execution.

Source

pub async fn run_migration_phases(self) -> Result<()>

Run only the migration phases (pre-init + DB migration).

This is designed for cloud deployment workflows where database migrations need to run as a separate step before starting the application. The process exits after migrations complete.

§Errors

Returns an error if pre-init or migration phases fail.
