Struct PowercapNodeInfo 

pub struct PowercapNodeInfo {
    pub node_id: Option<u64>,
    pub parent_node_id: Option<u64>,
    pub zone_path: Option<String>,
    pub name: Option<String>,
    pub constraint_name: Option<String>,
    pub max_power_uw: Option<u64>,

    pub supports_bypass: Option<bool>,
    /* private fields */
}

Describes the static topology and attributes of a single powercap zone node.

node_id, zone_path, and name must always be present on every node; entries omitting any of these fields are ignored by clients.

Fields

node_id: Option<u64>

Unique identifier for this node within the powercap tree. Required.

parent_node_id: Option<u64>

The node_id of the parent zone. Omitted for root zones (e.g., gpc:0).

zone_path: Option<String>

The canonical sysfs directory name under /sys/class/powercap (e.g., "gpc:0", "gpc:0:0", "gpc:0:0:0"). Required.

name: Option<String>

The logical zone name exposed via the name sysfs attribute (e.g., "gpc", "TestZone", "BIG", "MID", "LITTLE", "GPU"). Required.

constraint_name: Option<String>

The constraint name exposed via constraint_0_name (e.g., "TestConstraint"). Omitted if the zone does not expose constraint metadata.

max_power_uw: Option<u64>

Maximum power limit in microwatts (constraint_0_max_power_uw). Omitted if the zone does not expose a maximum power limit attribute.

min_power_uw: Option<u64>

Minimum power limit in microwatts (constraint_0_min_power_uw). Omitted if the zone does not expose a minimum power limit attribute.

power_levels_uw: Option<Vec<u64>>

Discrete supported power levels in microwatts (power_levels_uw), ordered from highest to lowest. Omitted for aggregator zones without discrete power tables.

supports_bypass: Option<bool>

Whether this zone exposes power_limit_bypass_msec for transient boost overrides (e.g., PowerHAL CPU_LOAD_SPIKE / LAUNCH hints). Omitted (or false) if the zone does not support bypass overrides.

Trait Implementations

impl Clone for PowercapNodeInfo

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PowercapNodeInfo

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<PowercapNodeInfo, D> for PowercapNodeInfo

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

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

impl Default for PowercapNodeInfo

fn default() -> Self

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<PowercapNodeInfo, D> for &PowercapNodeInfo

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, 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 PowercapNodeInfo

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

Equality operator ==.

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

Inequality operator !=.

impl Persistable for PowercapNodeInfo

impl StructuralPartialEq for PowercapNodeInfo

impl TypeMarker for PowercapNodeInfo

type Owned = PowercapNodeInfo

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 PowercapNodeInfo

type Borrowed<'a> = &'a PowercapNodeInfo

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: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

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