Struct fidl_fuchsia_component_decl::OfferStorage

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

Declares a storage capability offered by a component to one of its children, such as meta storage offered by the component’s containing realm or cache storage offered by the component itself.

Fields

source_name: Option<String>

(Required) The name of the storage capability being offered

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.

target: Option<Ref>

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

target_name: Option<String>

(Required) The name the storage capability is being offered as

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.

Trait Implementations

impl Clone for OfferStorage

fn clone(&self) -> OfferStorage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OfferStorage

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

Formats the value using the given formatter.

impl Decode<OfferStorage> for OfferStorage

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 OfferStorage

fn default() -> OfferStorage

Returns the “default value” for a type.

impl Encode<OfferStorage> for &OfferStorage

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 OfferStorage

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

type Owned = OfferStorage

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 OfferStorage

type Borrowed<'a> = &'a OfferStorage

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.
