Fields

source: Option<ChildSource>

The runtime source for creating this child.

Required.

name: Option<String>

The name of this child local to its containing realm.

Required.

exposes: Option<Vec<String>>

Protocols that this child exposes to the realm.

If not set, interpreted as an empty vector.

uses: Option<ChildUses>

Capabilities that this child uses.

If not set, no capabilities will be routed to the component.

program_args: Option<Vec<String>>

Arguments to be passed to the child at runtime. If specified, overrides any arguments specified in the manifest.

If not set, the original arguments from the manifest are used.

eager: Option<bool>

Whether the component should be started eagerly once the realm is created.

If not set, interpreted as false.

config_values: Option<Vec<ChildConfigValue>>

Structured configuration values to override when launching the child.

If not set, interpereted as an empty vector.

Trait Implementations

impl Debug for ChildDef

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

Formats the value using the given formatter.

impl Decode<ChildDef, DefaultFuchsiaResourceDialect> for ChildDef

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 Default for ChildDef

fn default() -> ChildDef

Returns the “default value” for a type.

impl Encode<ChildDef, DefaultFuchsiaResourceDialect> for &mut ChildDef

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 PartialEq for ChildDef

fn eq(&self, other: &ChildDef) -> 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 ResourceTypeMarker for ChildDef

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

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 ChildDef

type Owned = ChildDef

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.
