Struct Spec 

pub struct Spec {
    pub design_capacity_uah: Option<u32>,
    pub design_voltage_uv: Option<u32>,
    pub chemistry: Option<String>,
    pub model: Option<String>,
    pub supported_options: Option<WatchOptions>,
    /* private fields */
}

Static hardware characteristics and driver capabilities.

Fields

design_capacity_uah: Option<u32>

Optional. Design capacity in microamp-hours. Omitted if unsupported by hardware.

design_voltage_uv: Option<u32>

Optional. Nominal design voltage in microvolts. Omitted if unsupported by hardware.

chemistry: Option<String>

Optional. Informational battery chemistry description (e.g. “Li-ion”, “LiFePO4”, “NiMH”). Omitted if unknown or unprogrammed in hardware.

model: Option<String>

Optional. Informational battery model string or manufacturer part number. Omitted if unknown or unprogrammed in hardware.

supported_options: Option<WatchOptions>

Required. The interest and wake options supported by this driver/hardware.

Drivers must populate this table so clients know which fields support active change notifications. If omitted by the driver, clients should assume no active interrupt watching is supported.

• supported_options.interest: Telemetry fields that can actively trigger hanging-get watch notifications on change. Fields omitted are passive measurements that do not generate hardware interrupts; their freshest values are returned during active state changes or via [Battery.GetStatus].
• supported_options.wake_on: Telemetry fields capable of actively waking the system from suspend via hardware interrupt lines etc.

Trait Implementations

impl Clone for Spec

fn clone(&self) -> Spec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Spec

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

Formats the value using the given formatter.

impl<D> Decode<Spec, D> for Spec

where D: ResourceDialect,

fn new_empty() -> Spec

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<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for Spec

fn default() -> Spec

Returns the “default value” for a type.

impl<D> Encode<Spec, D> for &Spec

where D: ResourceDialect,

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for Spec

fn eq(&self, other: &Spec) -> bool

Equality operator ==.

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

Inequality operator !=.

impl Persistable for Spec

impl StructuralPartialEq for Spec

impl TypeMarker for Spec

type Owned = Spec

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.

impl ValueTypeMarker for Spec

type Borrowed<'a> = &'a Spec

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow( value: &<Spec as TypeMarker>::Owned, ) -> <Spec as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
