Struct GpuCounterDescriptor 

pub struct GpuCounterDescriptor {
    pub specs: Vec<GpuCounterSpec>,
    pub blocks: Vec<GpuCounterBlock>,
    pub counter_groups: Vec<GpuCounterGroupSpec>,
    pub min_sampling_period_ns: Option<u64>,

}

Description of GPU counters. This message is sent by a GPU counter producer to specify the counters available in the hardware.

Fields

specs: Vec<GpuCounterSpec>

blocks: Vec<GpuCounterBlock>

counter_groups: Vec<GpuCounterGroupSpec>

min_sampling_period_ns: Option<u64>

optional. Minimum sampling period supported by the producer in nanoseconds.

max_sampling_period_ns: Option<u64>

optional. Maximum sampling period supported by the producer in nanoseconds.

supports_instrumented_sampling: Option<bool>

optional. The producer supports counter sampling by instrumenting the command buffer.

supports_counter_names: Option<bool>

optional. The producer supports selecting counters by name via GpuCounterConfig.counter_names. Not all producers support this; Android GPU producers typically do not.

supports_counter_name_globs: Option<bool>

optional. The producer supports glob patterns in GpuCounterConfig.counter_names for matching multiple counters by name.

Implementations

impl GpuCounterDescriptor

pub fn min_sampling_period_ns(&self) -> u64

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

pub fn max_sampling_period_ns(&self) -> u64

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

pub fn supports_instrumented_sampling(&self) -> bool

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

pub fn supports_counter_names(&self) -> bool

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

pub fn supports_counter_name_globs(&self) -> bool

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

Trait Implementations

impl Clone for GpuCounterDescriptor

fn clone(&self) -> GpuCounterDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuCounterDescriptor

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

Formats the value using the given formatter.

impl Default for GpuCounterDescriptor

fn default() -> Self

Returns the “default value” for a type.

impl Message for GpuCounterDescriptor

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,

impl PartialEq for GpuCounterDescriptor

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