Struct StartChildArgs

pub struct StartChildArgs {
    pub numbered_handles: Option<Vec<HandleInfo>>,
    pub namespace_entries: Option<Vec<NamespaceEntry>>,
    pub dictionary: Option<DictionaryRef>,
    /* private fields */
}

Fields

numbered_handles: Option<Vec<HandleInfo>>

The numbered handles to pass to the component instance.

If the runner for the component does not support the numbered handles it is expected to close the handles.

If set, the values given here will override the handles given in CreateChildArgs.

namespace_entries: Option<Vec<NamespaceEntry>>

The namespace generated by component manager will be extended to include any namespace entries listed here before being given to the component’s runner.

If there are any conflicting entries, an error will occur when starting the component.

dictionary: Option<DictionaryRef>

A dictionary that contains extra capabilities for the component instance.

Trait Implementations

impl Debug for StartChildArgs

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

Formats the value using the given formatter.

impl Decode<StartChildArgs, DefaultFuchsiaResourceDialect> for StartChildArgs

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 StartChildArgs

fn default() -> StartChildArgs

Returns the “default value” for a type.

impl Encode<StartChildArgs, DefaultFuchsiaResourceDialect> for &mut StartChildArgs

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 StartChildArgs

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

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

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 StartChildArgs

type Owned = StartChildArgs

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.
