Arguments for starting a driver.

Fields

node: Option<ClientEnd<NodeMarker>>

Node that the driver is bound to.

symbols: Option<Vec<NodeSymbol>>

Symbols provided to the driver, for |node|. These come from the driver that added |node|, and are filtered to the symbols requested in the bind program.

url: Option<String>

URL of the package containing the driver. This is purely informational, used only to provide data for inspect.

program: Option<Dictionary>

Information about the driver to start. Currently, we support the following entries:

1. “binary”: a string containing the package-relative path to the driver binary.
2. “colocate” (optional): a string containing “true” or “false” specifying whether the driver should be colocated in the same driver host as the driver that added |node|. If not specified, the driver will be launched in a new driver host.
3. “default_dispatcher_opts” (optional): an array of strings specifying the options for creating the default dispatcher. A string can be one of the following:
   • allow_sync_calls: allows synchronous calls to be done on the default dispatcher’s thread.
4. “default_dispatcher_scheduler_role” (optional): the scheduler role to set for the default dispatcher created for the driver.

incoming: Option<Vec<ComponentNamespaceEntry>>

Incoming namespace provided to the driver.

outgoing_dir: Option<ServerEnd<DirectoryMarker>>

Outgoing directory served by the driver.

config: Option<Vmo>

Configuration passed to the driver.

node_name: Option<String>

The name of the node the driver is bound to.

node_properties: Option<Vec<NodePropertyEntry>>

Node properties of the node the driver is bound to. If the node is non-composite then the “default” entry will contain the node’s own properties. If the node is a composite then there is an entry for each of its parents and the “default” entry will reference the primary composite parent node’s properties. The composite parent node’s properties are those that were provided in the composite node specification and not the original properties of the parent.

node_offers: Option<Vec<Offer>>

Node offers of the node the driver is bound to.

node_token: Option<Event>

Provides a token representing this node which can be exchanged with the driver framework to discern additional information about this node.

node_properties_2: Option<Vec<NodePropertyEntry2>>

Trait Implementations

impl Debug for DriverStartArgs

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

Formats the value using the given formatter.

impl Decode<DriverStartArgs, DefaultFuchsiaResourceDialect> for DriverStartArgs

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 DriverStartArgs

fn default() -> DriverStartArgs

Returns the “default value” for a type.

impl Encode<DriverStartArgs, DefaultFuchsiaResourceDialect> for &mut DriverStartArgs

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 DriverStartArgs

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

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

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 DriverStartArgs

type Owned = DriverStartArgs

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.
