Struct fidl_fuchsia_component_decl::OfferConfiguration

pub struct OfferConfiguration {
    pub source: Option<Ref>,
    pub source_name: Option<String>,
    pub target: Option<Ref>,
    pub target_name: Option<String>,
    pub availability: Option<Availability>,
    pub source_dictionary: Option<String>,
    /* private fields */
}

Declares a configuration capability offered by a component to one of its children, which may have been offered by the component’s containing realm, the component itself, or one of its other children.

Fields

source: Option<Ref>

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

source_name: Option<String>

(Required) Name identifying the configuration being offered.

target: Option<Ref>

(Required) Reference to the target. Must be child, or collection.

target_name: Option<String>

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

availability: Option<Availability>

(Optional, defaults to REQUIRED) The availability of this capability. If set to required, the target may use or offer the capability with either required or optional availability. If set to optional, the target must use or offer the capability with optional availability. The same_as_target value causes this offer’s availability to match the availability set in the target.

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 OfferConfiguration

fn clone(&self) -> OfferConfiguration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OfferConfiguration

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

Formats the value using the given formatter.

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

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 OfferConfiguration

fn default() -> OfferConfiguration

Returns the “default value” for a type.

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

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 OfferConfiguration

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

type Owned = OfferConfiguration

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 OfferConfiguration

type Borrowed<'a> = &'a OfferConfiguration

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.
