Struct Storage

pub struct Storage {
    pub name: Option<String>,
    pub source: Option<Ref>,
    pub backing_dir: Option<String>,
    pub subdir: Option<String>,
    pub storage_id: Option<StorageId>,
    /* private fields */
}

Declares a storage capability backed by a directory from which data, cache, or meta storage can be offered.

Fields

name: Option<String>

(Required) The name of this storage

source: Option<Ref>

(Required) The provider of the backing directory capability relative to the component itself. Must be parent, self, or child.

backing_dir: Option<String>

(Required) The name of the directory capability from source that backs the storage.

subdir: Option<String>

(Optional) The subdirectory of the source directory that will back the storage

storage_id: Option<StorageId>

(Required) This enum determines how to key a component’s isolated storage directory. Each option corresponds to a different key’ing strategy.

Trait Implementations

impl Clone for Storage

fn clone(&self) -> Storage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Storage

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

Formats the value using the given formatter.

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

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 Storage

fn default() -> Storage

Returns the “default value” for a type.

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

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 Storage

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

type Owned = Storage

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 Storage

type Borrowed<'a> = &'a Storage

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 Storage
