Runtime configuration options. This configuration intended to be “global”, in that the same configuration is applied throughout a given running instance of component_manager.

Fields

list_children_batch_size: usize

How many children, maximum, are returned by a call to ChildIterator.next().

security_policy: Arc<SecurityPolicy>

Security policy configuration.

debug: bool

If true, component manager will be in debug mode. In this mode, component manager provides the EventSource protocol and exposes this protocol. The root component must be manually started using the LifecycleController protocol in the hub.

This is done so that an external component (say an integration test) can subscribe to events before the root component has started.

enable_introspection: bool

Enables Component Manager’s introspection APIs (RealmQuery, RealmExplorer, RouteValidator, LifecycleController, etc.) for use by components.

use_builtin_process_launcher: bool

If true, component_manager will serve an instance of fuchsia.process.Launcher and use this launcher for the built-in ELF component runner. The root component can additionally use and/or offer this service using ‘/builtin/fuchsia.process.Launcher’ from realm.

maintain_utc_clock: bool

If true, component_manager will maintain a UTC kernel clock and vend write handles through an instance of fuchsia.time.Maintenance. This flag should only be used with the top-level component_manager.

num_threads: usize

namespace_capabilities: Vec<CapabilityDecl>

The list of capabilities offered from component manager’s namespace.

builtin_capabilities: Vec<CapabilityDecl>

The list of capabilities offered from component manager as built-in capabilities.

root_component_url: Option<Url>

URL of the root component to launch. This field is used if no URL is passed to component manager. If value is passed in both places, then an error is raised.

component_id_index_path: Option<Utf8PathBuf>

Path to the component ID index, parsed from fuchsia.component.internal.RuntimeConfig.component_id_index_path.

log_destination: LogDestination

Where to log to.

log_all_events: bool

If true, component manager will log all events dispatched in the topology.

builtin_boot_resolver: BuiltinBootResolver

Which builtin resolver to use for the fuchsia-boot scheme. If not supplied this defaults to the NONE option.

realm_builder_resolver_and_runner: RealmBuilderResolverAndRunner

If and how the realm builder resolver and runner are enabled.

abi_revision_policy: AbiRevisionPolicy

The enforcement and validation policy to apply to component target ABI revisions.

vmex_source: VmexSource

Where to get the vmex resource from.

Implementations

impl RuntimeConfig

pub fn new_from_bytes(bytes: &Vec<u8>) -> Result<Self, Error>

Trait Implementations

impl Debug for RuntimeConfig

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

Formats the value using the given formatter.

impl Default for RuntimeConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for RuntimeConfig

fn eq(&self, other: &RuntimeConfig) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<Config> for RuntimeConfig

type Error = Error

The type returned in the event of a conversion error.

fn try_from(config: Config) -> Result<Self, Error>

Performs the conversion.

impl Eq for RuntimeConfig

impl StructuralPartialEq for RuntimeConfig
