Struct ImportResourceCmdDeprecated

pub struct ImportResourceCmdDeprecated {
    pub id: u32,
    pub token: EventPair,
    pub spec: ImportSpec,
}

Import a resource that was exported via ExportResourceCmd(). token is a handle to the eventpair peer that was used to export the resource, and spec describes the type of the imported resource, and the commands which can legally be applied to it. Afterward, id can be used to refer to the resource in an Command, similarly (but not identically: see below) to a resource that was created in the session. For example, you can add children to an imported EntityNode via AddChildCmd.

However, note that the importer does not gain full access to the imported resource, but rather to an attenuated subset of its capabilities. For example, you cannot use a DetachCmd to detach an imported EntityNode from its parent.

Unlike ExportResourceCmd, there is no configurable timeout. There is an expectation that the exported resource will become available in a short amount of time. TODO: this needs elaboration… e.g. we might notify via the SessionListener when we know that the link will never be made (e.g. if the peer of the import token is destroyed).

Trait Implementations

impl Debug for ImportResourceCmdDeprecated

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

Formats the value using the given formatter.

impl Decode<ImportResourceCmdDeprecated, DefaultFuchsiaResourceDialect> for ImportResourceCmdDeprecated

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<'_, DefaultFuchsiaResourceDialect>, offset: usize, _depth: Depth, ) -> Result<()>

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

impl Encode<ImportResourceCmdDeprecated, DefaultFuchsiaResourceDialect> for &mut ImportResourceCmdDeprecated

unsafe fn encode( self, encoder: &mut Encoder<'_, DefaultFuchsiaResourceDialect>, 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<T0: Encode<u32, DefaultFuchsiaResourceDialect>, T1: Encode<HandleType<EventPair, { _ }, 2147483648>, DefaultFuchsiaResourceDialect>, T2: Encode<ImportSpec, DefaultFuchsiaResourceDialect>> Encode<ImportResourceCmdDeprecated, DefaultFuchsiaResourceDialect> for (T0, T1, T2)

unsafe fn encode( self, encoder: &mut Encoder<'_, DefaultFuchsiaResourceDialect>, 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 Hash for ImportResourceCmdDeprecated

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ImportResourceCmdDeprecated

fn cmp(&self, other: &ImportResourceCmdDeprecated) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ImportResourceCmdDeprecated

fn eq(&self, other: &ImportResourceCmdDeprecated) -> 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 PartialOrd for ImportResourceCmdDeprecated

fn partial_cmp(&self, other: &ImportResourceCmdDeprecated) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl ResourceTypeMarker for ImportResourceCmdDeprecated

type Borrowed<'a> = &'a mut ImportResourceCmdDeprecated

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &mut Self::Owned. There are three cases:

fn take_or_borrow<'a>( value: &'a mut <Self as TypeMarker>::Owned, ) -> Self::Borrowed<'a>

Cheaply converts from &mut Self::Owned to Self::Borrowed. For HandleBased types this is “take” (it returns an owned handle and replaces value with Handle::invalid), and for all other types it is “borrow” (just converts from one reference to another).

impl TypeMarker for ImportResourceCmdDeprecated

type Owned = ImportResourceCmdDeprecated

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.
