Struct UseStorage

pub struct UseStorage {
    pub source_name: Option<String>,
    pub target_path: Option<String>,
    pub availability: Option<Availability>,
    /* private fields */
}

Declares storage used by a component, which was offered to it.

Fields

source_name: Option<String>

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

target_path: Option<String>

(Required) The path where the capability should be installed in the component’s namespace.

Must be an absolute path starting with /.

availability: Option<Availability>

(Optional, defaults to REQUIRED) The availability of this capability. If set to required, the component is likely to malfunction if this capability is not provided. If set to optional, the component can handle the capability’s absence.

Trait Implementations

impl Clone for UseStorage

fn clone(&self) -> UseStorage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UseStorage

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

Formats the value using the given formatter.

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

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 UseStorage

fn default() -> UseStorage

Returns the “default value” for a type.

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

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 UseStorage

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

type Owned = UseStorage

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 UseStorage

type Borrowed<'a> = &'a UseStorage

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.
