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_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>>

vmar: Option<Vmar>

Root VMAR the driver is mapped into. All child mappings should be placed into this VMAR if they want to have the same scheduler profile applied to them.

power_element_args: Option<PowerElementArgs>

Handles related to the driver’s power elements on products where suspend is enabled by the fuchsia.power.SuspendEnabled config capability. If the driver’s manifest contains suspend_enabled = "true" in the program section of its manifest, the element_server, lessor_client, and token are passed to the driver, otherwise the handles are retained by the driver host. control_client is always retained by the driver host and never passed to the driver.

log_sink: Option<ClientEnd<LogSinkMarker>>

Log sink channel.

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() -> Self

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: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

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 Standalone<DefaultFuchsiaResourceDialect> for DriverStartArgs

impl StructuralPartialEq for DriverStartArgs

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.
