Struct ConcurrentSessionEvent 

pub struct ConcurrentSessionEvent {
    pub state: Option<i32>,
    pub session_name: Option<String>,
    pub session_id: Option<u64>,
    pub consumer_uid: Option<i32>,
    pub num_data_sources: Option<u32>,
}

Emitted by the tracing service to record a state change of another tracing session that was active while this trace was being recorded. Opt-in via TraceConfig.BuiltinDataSource.enable_concurrent_session_events.

One packet per state change; its time is carried by the enclosing TracePacket’s timestamp (CLOCK_BOOTTIME). Events of the same session share the same |session_id|. The trace UUID is deliberately not included.

Introduced in v58 / Android 26Q3+.

Fields

state: Option<i32>

The state the session transitioned to at this timestamp.

session_name: Option<String>

unique_session_name from the session’s TraceConfig. May be empty.

session_id: Option<u64>

Service-local monotonic counter identifying the session. Shared by all state changes of one session, never reused within a service instance.

consumer_uid: Option<i32>

Unix uid of the consumer that started the session.

num_data_sources: Option<u32>

Number of data sources in the session at the time of the state change.

Implementations

impl ConcurrentSessionEvent

pub fn state(&self) -> State

Returns the enum value of state, or the default if the field is unset or set to an invalid enum value.

pub fn set_state(&mut self, value: State)

Sets state to the provided enum value.

pub fn session_name(&self) -> &str

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

pub fn session_id(&self) -> u64

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

pub fn consumer_uid(&self) -> i32

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

pub fn num_data_sources(&self) -> u32

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

Trait Implementations

impl Clone for ConcurrentSessionEvent

fn clone(&self) -> ConcurrentSessionEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConcurrentSessionEvent

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

Formats the value using the given formatter.

impl Default for ConcurrentSessionEvent

fn default() -> Self

Returns the “default value” for a type.

impl Eq for ConcurrentSessionEvent

impl Hash for ConcurrentSessionEvent

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for ConcurrentSessionEvent

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(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where 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( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where 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(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

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

where Self: Default,

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

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

where Self: Sized,

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

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

where Self: Sized,

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

impl PartialEq for ConcurrentSessionEvent

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