Struct Child

pub struct Child {
    pub name: Option<String>,
    pub url: Option<String>,
    pub startup: Option<StartupMode>,
    pub environment: Option<String>,
    pub on_terminate: Option<OnTerminate>,
    pub config_overrides: Option<Vec<ConfigOverride>>,
    /* private fields */
}

Statically declares a child component instance.

Fields

name: Option<String>

(Required) The name assigned to the child by its parent.

Must be non-empty, unique among all siblings, and contain only the following characters: [a-z0-9-_.].

url: Option<String>

(Required) The child component’s URL.

Must be non-empty and a well-formed URL.

startup: Option<StartupMode>

(Required) The startup mode for the component instance.

Must be set.

environment: Option<String>

(Optional) The environment assigned to this child.

May be unset, in which case the child will inherit the parent component’s environment. If set, the name must reference an environment defined in the ComponentDecl and it must contain only the following characters: [a-z0-9-_.].

on_terminate: Option<OnTerminate>

(Optional, defaults to NONE) The action to take if this component instance terminates unexpectedly.

config_overrides: Option<Vec<ConfigOverride>>

Configuration overrides to apply to the child’s base configuration.

For a configuration field to be overridden it must be marked as mutable by parent.

Parents must pass ConfigOverride values which match the child’s declared schema types exactly.

Trait Implementations

impl Clone for Child

fn clone(&self) -> Child

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Child

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

Formats the value using the given formatter.

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

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 Child

fn default() -> Child

Returns the “default value” for a type.

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

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 Child

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

type Owned = Child

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 Child

type Borrowed<'a> = &'a Child

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.
