Fields

connector: Option<ClientEnd<ConnectorMarker>>

This is the connector to be installed in devfs. Connect() will be called when a client connects to this node in the filesystem. Optional: If this is not provided then an empty node will appear in devfs.

class_name: Option<String>

This is the class name for installing this node in devfs. The node will be placed within /dev/class/{class_name}. If class_name does not exist under /dev/class/ it will be created. Optional: If this is not provided then the node will only be added via topological path.

inspect: Option<Vmo>

This is a vmo of inspect data that will be installed in devfs. Optional: If this is not provided then the devfs’s inspect data will be empty.

connector_supports: Option<ConnectionType>

The connection types that are supported by the |connector| given. The driver framework should handle connection types that are not supported by the connector. If not provided, only the device type is assumed as supported by the connector.

controller_connector: Option<ClientEnd<ConnectorMarker>>

This is the controller connector to be installed in devfs. Connect() will be called when a client connects to the device_controller connection for this node in the filesystem. Optional: If this is not provided then the Node will handle the connection natively. This option should only be used by the compat shim or in tests

Trait Implementations

impl Debug for DevfsAddArgs

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

Formats the value using the given formatter.

impl Decode<DevfsAddArgs, DefaultFuchsiaResourceDialect> for DevfsAddArgs

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 DevfsAddArgs

fn default() -> DevfsAddArgs

Returns the “default value” for a type.

impl Encode<DevfsAddArgs, DefaultFuchsiaResourceDialect> for &mut DevfsAddArgs

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 DevfsAddArgs

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

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

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 DevfsAddArgs

type Owned = DevfsAddArgs

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.
