Fields

debug: Option<bool>

If true, component manager will be in debug mode. In this mode, component manager provides the EventSource protocol and exposes this protocol. Component manager will not start until it is resumed by a call to EventSource.StartComponentTree.

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

list_children_batch_size: Option<u32>

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

security_policy: Option<SecurityPolicy>

Security policy configuration.

namespace_capabilities: Option<Vec<Capability>>

Capabilities offered from component manager’s namespace.

use_builtin_process_launcher: Option<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. This flag exists because the built-in process launcher only works when component_manager runs under a job that has ZX_POL_NEW_PROCESS set to allow, like the root job. Otherwise, the component_manager process cannot directly create process through zx_process_create. When we run component_manager elsewhere, like in test environments, it has to use the fuchsia.process.Launcher service provided through its namespace instead.

maintain_utc_clock: Option<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: Option<u32>

The number of threads to use for running component_manager’s executor. If not present, interpreted as 1.

root_component_url: Option<String>

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

component_id_index_path: Option<String>

Path to the component ID index. An empty value defaults to an empty index. An invalid index causes component_manager to abort.

log_destination: Option<LogDestination>

Where to log to.

log_all_events: Option<bool>

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

builtin_boot_resolver: Option<BuiltinBootResolver>

Which builtin resolver to use for the fuchsia-boot scheme. If not present, interpreted as BuiltinBootResolver.NONE.

realm_builder_resolver_and_runner: Option<RealmBuilderResolverAndRunner>

If and how the realm builder resolver and runner will be used. Typically these capabilities from realm builder are available to a nested component manager that is undergoing an integration test.

builtin_capabilities: Option<Vec<Capability>>

Capabilities offered from component manager as built-in capabilities.

enable_introspection: Option<bool>

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

abi_revision_policy: Option<AbiRevisionPolicy>

The enforcement and validation policy to apply to component target ABI revisions. If not present, defaults to AbiRevisionPolicy::ENFORCE_PRESENCE_AND_COMPATIBILITY.

vmex_source: Option<VmexSource>

Where to obtain the vmex resource from, if this component_manager is hosting bootfs. If not present, defaults to VmexSource::SYSTEM_RESOURCE.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Config

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

Formats the value using the given formatter.

impl Decode<Config> for Config

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_>, offset: usize, depth: Depth ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for Config

fn default() -> Config

Returns the “default value” for a type.

impl Encode<Config> for &Config

unsafe fn encode( self, encoder: &mut Encoder<'_>, offset: usize, depth: Depth ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for Config

fn eq(&self, other: &Config) -> 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 TypeMarker for Config

type Owned = Config

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for Config

type Borrowed<'a> = &'a Config

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow<'a>(value: &'a <Self as TypeMarker>::Owned) -> Self::Borrowed<'a>

Cheaply converts from &Self::Owned to Self::Borrowed.

impl Persistable for Config

impl StructuralPartialEq for Config
