Struct fuchsia_component_test::RealmInstance

pub struct RealmInstance {
    pub root: ScopedInstance,
    /* private fields */
}

A running instance of a created realm. When this struct is dropped the realm is destroyed, along with any components that were in the realm.

Fields

root: ScopedInstance

The root component of this realm instance, which can be used to access exposed capabilities from the realm.

Implementations

impl RealmInstance

pub async fn destroy(self) -> Result<(), Error>

Destroys the realm instance, returning only once realm destruction is complete.

This function can be useful to call when it’s important to ensure a realm accessing a global resource is stopped before proceeding, or to ensure that realm destruction doesn’t race with process (and thus local component implementations) termination.

pub async fn start_component_tree(&self) -> Result<(), Error>

Connects to the fuchsia.sys2.LifecycleController protocol exposed by a nested component manager and attempts to start the root component. This should only be used when a realm is built in a nested component manager in debug mode.

Trait Implementations

impl Drop for RealmInstance

fn drop(&mut self)

To ensure local components are shutdown in an orderly manner (i.e. after their dependent clients) upon drop, keep the local_component_runner_task alive in an async task until the destroy_waiter synchronously destroys the realm.

Remember that you must keep a life reference to a RealmInstance to ensure that your realm stays running.
