Struct Instance 

pub struct Instance {
    pub moniker: Option<String>,
    pub url: Option<String>,
    pub instance_id: Option<String>,
    pub resolved_info: Option<ResolvedInfo>,
    pub environment: Option<String>,
    /* private fields */
}

Describes a component instance under a realm.

Note: This structure is expected to fit in a single Zircon channel message. Do not add fields that have the potential to violate that constraint. Prefer to create dedicated methods and iterators instead.

Fields

moniker: Option<String>

The path to this instance relative to the scope root.

url: Option<String>

The URL of the component manifest for this instance.

instance_id: Option<String>

The stable identifier for this instance, if one exists.

resolved_info: Option<ResolvedInfo>

Information about the resolved state of a component instance. If the component is not resolved, this field is not set.

environment: Option<String>

The component’s environment name as defined by its parent.

Trait Implementations

impl Clone for Instance

fn clone(&self) -> Instance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Instance

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

Formats the value using the given formatter.

impl<D> Decode<Instance, D> for Instance

where D: ResourceDialect,

fn new_empty() -> Instance

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<(), Error>

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

impl Default for Instance

fn default() -> Instance

Returns the “default value” for a type.

impl<D> Encode<Instance, D> for &Instance

where D: ResourceDialect,

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for Instance

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

type Owned = Instance

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 Instance

type Borrowed<'a> = &'a Instance

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: &<Instance as TypeMarker>::Owned, ) -> <Instance as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
