Passed to Topology.AddElement.

Fields

element_name: Option<String>

Human-readable name for logging and debug purposes.

initial_current_level: Option<u8>

The initial current power level of the element.

valid_levels: Option<Vec<u8>>

All power levels that are valid for this element. Any level not specified here will be treated as invalid.

dependencies: Option<Vec<LevelDependency>>

List of dependencies for this element’s power levels. Note: dependencies UPON this element’s levels cannot be added here.

level_control_channels: Option<LevelControlChannels>

Channels on which Power Broker will send required power levels and receive current level updates.

lessor_channel: Option<ServerEnd<LessorMarker>>

Optional. If passed, this will be treated as a consumer element and Leases for this element can be requested via this channel.

element_control: Option<ServerEnd<ElementControlMarker>>

Caller-provided ElementControl channel to be passed to Power Broker. When this channel is dropped, the element will be removed from the topology. All channels associated with this element will be closed and all tokens registered to this element will be unregistered.

Trait Implementations

impl Debug for ElementSchema

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

Formats the value using the given formatter.

impl Decode<ElementSchema, DefaultFuchsiaResourceDialect> for ElementSchema

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 ElementSchema

fn default() -> ElementSchema

Returns the “default value” for a type.

impl Encode<ElementSchema, DefaultFuchsiaResourceDialect> for &mut ElementSchema

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 ElementSchema

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

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

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 ElementSchema

type Owned = ElementSchema

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.
