Struct perfetto_consumer_proto::perfetto::protos::TracingServiceCapabilities

pub struct TracingServiceCapabilities {
    pub has_query_capabilities: Option<bool>,
    pub observable_events: Vec<i32>,
    pub has_trace_config_output_path: Option<bool>,
    pub has_clone_session: Option<bool>,
}

Fields

has_query_capabilities: Option<bool>

Whether the service supports QueryCapabilities() at all or not. This is only used at the C++ level to distinguish the case of talking to an older version of the service that doesn’t support QueryCapabilities(). In that case the IPC layer will just reject the unknown call, and the consumer_ipc_client_impl.cc will return an empty message where this field is false. In all other cases, this is always set to true.

observable_events: Vec<i32>

The set of known events that can be passed to ConsumerPort.ObserveEvents().

has_trace_config_output_path: Option<bool>

Whether the service supports TraceConfig.output_path (for asking traced to create the output file instead of passing a file descriptor).

has_clone_session: Option<bool>

Whether the service supports CloneSession and CLONE_SNAPSHOT triggers.

Implementations

impl TracingServiceCapabilities

pub fn has_query_capabilities(&self) -> bool

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

pub fn observable_events( &self, ) -> FilterMap<Cloned<Iter<'_, i32>>, fn(_: i32) -> Option<Type>>

Returns an iterator which yields the valid enum values contained in observable_events.

pub fn push_observable_events(&mut self, value: Type)

Appends the provided enum value to observable_events.

pub fn has_trace_config_output_path(&self) -> bool

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

pub fn has_clone_session(&self) -> bool

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

Trait Implementations

impl Clone for TracingServiceCapabilities

fn clone(&self) -> TracingServiceCapabilities

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TracingServiceCapabilities

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

Formats the value using the given formatter.

impl Default for TracingServiceCapabilities

fn default() -> Self

Returns the “default value” for a type.

impl Message for TracingServiceCapabilities

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 TracingServiceCapabilities

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
