Metadata for chrome traces.

Fields

background_tracing_metadata: Option<BackgroundTracingMetadata>

chrome_version_code: Option<i32>

Version code of Chrome used by Android’s Play Store. This field is only set on Android.

enabled_categories: Option<String>

Comma separated list of enabled categories for tracing. The list of possible category strings are listed in code base/trace_event/builtin_categories.h.

field_trial_hashes: Vec<FinchHash>

List of Finch study/groups that apply to this trace.

app_package_name: Option<String>

The package name of the app which is being traced. This field is only set on Android.

app_version: Option<String>

A version number string for Chrome. This matches SystemProfileProto::app_version.

channel: Option<u32>

This matches SystemProfileProto::channel.

os_name: Option<String>

The user’s operating system. This matches SystemProfileProto::OS::name.

Implementations

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

pub fn enabled_categories(&self) -> &str

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

pub fn app_package_name(&self) -> &str

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

pub fn app_version(&self) -> &str

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

pub fn channel(&self) -> u32

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

pub fn os_name(&self) -> &str

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

Trait Implementations

impl Clone for ChromeMetadataPacket

fn clone(&self) -> ChromeMetadataPacket

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChromeMetadataPacket

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

Formats the value using the given formatter.

impl Default for ChromeMetadataPacket

fn default() -> Self

Returns the “default value” for a type.

impl Message for ChromeMetadataPacket

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 ChromeMetadataPacket

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