Struct fidl_fuchsia_component_decl::ExposeService

pub struct ExposeService {
    pub source: Option<Ref>,
    pub source_name: Option<String>,
    pub target: Option<Ref>,
    pub target_name: Option<String>,
    pub availability: Option<Availability>,

}

Declares a service exposed to a component’s containing realm, such as a service exposed by the component or one of its children at runtime.

To learn more about services, see: https://fuchsia.dev/fuchsia-src/glossary#service

Fields

source: Option<Ref>

(Required) The provider of the capability relative to the component itself. Must be self or child, or void. If set to void, then the target must expose, offer, or use the capability with OPTIONAL or TRANSITIONAL availability.

source_name: Option<String>

(Required) Name identifying the service, by which it was presented to this component.

target: Option<Ref>

(Required) The destination to which the service is exposed: either the component’s realm or the framework.

target_name: Option<String>

(Required) The name by which the capability is being exposed.

availability: Option<Availability>

(Optional, defaults to REQUIRED) The availability of this capability. See Availability.

source_dictionary: Option<String>

(Optional) Path in a dictionary provided by source which contains source_name. If this field is absent, source_name identifies a capability directly routed by source. If set, source_name identifies a capability nested inside this dictionary.

Trait Implementations

impl Clone for ExposeService

fn clone(&self) -> ExposeService

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExposeService

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<ExposeService, D> for ExposeService

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<'_, D>, offset: usize, depth: Depth, ) -> Result<()>

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

impl Default for ExposeService

fn default() -> ExposeService

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<ExposeService, D> for &ExposeService

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, 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 ExposeService

fn eq(&self, other: &ExposeService) -> 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 ExposeService

type Owned = ExposeService

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 ExposeService

type Borrowed<'a> = &'a ExposeService

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(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

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

impl Persistable for ExposeService

impl StructuralPartialEq for ExposeService
