Describes the source of a capability, as determined by find_capability_source

Variants

Component(ComponentSource)

This capability originates from the component instance for the given Realm. point.

Framework(FrameworkSource)

This capability originates from “framework”. It’s implemented by component manager and is scoped to the realm of the source.

Builtin(BuiltinSource)

This capability originates from the parent of the root component, and is built in to component manager. top_instance is the instance at the top of the tree, i.e. the instance representing component manager.

Namespace(NamespaceSource)

This capability originates from the parent of the root component, and is offered from component manager’s namespace. top_instance is the instance at the top of the tree, i.e. the instance representing component manager.

Capability(CapabilityToCapabilitySource)

This capability is provided by the framework based on some other capability.

AnonymizedAggregate(AnonymizedAggregateSource)

This capability is an aggregate of capabilities over a set of collections and static children. The instance names in the aggregate service will be anonymized.

FilteredProvider(FilteredProviderSource)

This capability is a filtered service capability from a single source, such as self or a child.

FilteredAggregateProvider(FilteredAggregateProviderSource)

This capability is a filtered service capability with multiple sources, such as all of the dynamic children in a collection. The instances in the aggregate service are the union of the filters.

Environment(EnvironmentSource)

This capability originates from “environment”. It’s implemented by a component instance.

Void(VoidSource)

This capability originates from “void”. This is only a valid origination for optional capabilities.

Implementations

impl CapabilitySource

pub fn can_be_in_namespace(&self) -> bool

Returns whether the given CapabilitySourceInterface can be available in a component’s namespace.

pub fn source_name(&self) -> Option<&Name>

pub fn type_name(&self) -> CapabilityTypeName

pub fn source_moniker(&self) -> ExtendedMoniker

Trait Implementations

impl Clone for CapabilitySource

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CapabilitySource

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

Formats the value using the given formatter.

impl Display for CapabilitySource

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

Formats the value using the given formatter.

impl FidlIntoNative<CapabilitySource> for CapabilitySource

fn fidl_into_native(self) -> CapabilitySource

impl NativeIntoFidl<CapabilitySource> for CapabilitySource

fn native_into_fidl(self) -> CapabilitySource

impl PartialEq for CapabilitySource

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<Capability> for CapabilitySource

type Error = Error

The type returned in the event of a conversion error.

fn try_from(capability: Capability) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<CapabilitySource> for Capability

type Error = Error

The type returned in the event of a conversion error.

fn try_from(capability_source: CapabilitySource) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<CapabilitySource> for Data

type Error = Error

The type returned in the event of a conversion error.

fn try_from(capability_source: CapabilitySource) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Data> for CapabilitySource

type Error = Error

The type returned in the event of a conversion error.

fn try_from(data: Data) -> Result<Self, Self::Error>

Performs the conversion.
