Struct GpuCounterEvent 

pub struct GpuCounterEvent {
    pub counters: Vec<GpuCounter>,
    pub gpu_id: Option<i32>,
    pub desc: Option<Desc>,
}

Events for emitting information about GPU counters.

There are two “modes” to use these protos:

1. Using GpuCounterDescriptor. This is the simplest way to use this proto but has the limitation that counter ids areglobal so must only be emitted by a single producer or requires coordination between different producers. This is the mechanism which must be used by Android OEMS to be complaint with CDD/CTS tests.
2. Using InternedGpuCounterDescriptor. This is generally recommended for more complex use-cases involving multiple producers, multiple GPUs etc.

Fields

counters: Vec<GpuCounter>

gpu_id: Option<i32>

Identifier for GPU in a multi-gpu device.

If counter_descriptor_iid is specified, the gpu_id in InternedGpuCounterDescriptor takes precedence over this field.

desc: Option<Desc>

The specification for the GPU counters. Gives them information like the name of the counter, unit etc.

Implementations

impl GpuCounterEvent

pub fn gpu_id(&self) -> i32

Returns the value of gpu_id, or the default value if gpu_id is unset.

Trait Implementations

impl Clone for GpuCounterEvent

fn clone(&self) -> GpuCounterEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuCounterEvent

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

Formats the value using the given formatter.

impl Default for GpuCounterEvent

fn default() -> Self

Returns the “default value” for a type.

impl Message for GpuCounterEvent

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for GpuCounterEvent

fn eq(&self, other: &GpuCounterEvent) -> 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.
