Fields

utsname: Option<Utsname>

android_build_fingerprint: Option<String>

android_soc_model: Option<String>

The SoC model from which trace is collected

android_hardware_revision: Option<String>

The hardware reversion from android device

android_storage_model: Option<String>

The storage component from android_device. This field has been introduced after Android W in Aug 2024 and is not supported on older versions.

android_ram_model: Option<String>

The RAM component information from android device. This field has been introduced after Android W in Aug 2024 and is not supported on older versions.

tracing_service_version: Option<String>

The version of traced (the same returned by traced --version). This is a human readable string with and its format varies depending on the build system and the repo (standalone vs AOSP). This is intended for human debugging only.

android_sdk_version: Option<u64>

The Android SDK vesion (e.g. 21 for L, 31 for S etc). Introduced in Android T.

page_size: Option<u32>

Kernel page size - sysconf(_SC_PAGESIZE).

num_cpus: Option<u32>

Number of cpus - sysconf(_SC_NPROCESSORS_CONF). Might be different to the number of online cpus. Introduced in perfetto v44.

timezone_off_mins: Option<i32>

The timezone offset from UTC, as per strftime(“%z”), in minutes. Introduced in v38 / Android V.

hz: Option<i64>

Ticks per second - sysconf(_SC_CLK_TCK). Not serialised as of perfetto v44.

Trait Implementations

impl Clone for SystemInfo

fn clone(&self) -> SystemInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SystemInfo

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

Formats the value using the given formatter.

impl Default for SystemInfo

fn default() -> Self

Returns the “default value” for a type.

impl Message for SystemInfo

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,

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 SystemInfo

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