}

Fields

utsname: Option<Utsname>

android_build_fingerprint: Option<String>

android_soc_model: Option<String>

The SoC model from which trace is collected

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.

Implementations

impl SystemInfo

pub fn android_build_fingerprint(&self) -> &str

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

pub fn hz(&self) -> i64

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

pub fn tracing_service_version(&self) -> &str

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

pub fn android_sdk_version(&self) -> u64

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

pub fn page_size(&self) -> u32

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

pub fn timezone_off_mins(&self) -> i32

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

pub fn num_cpus(&self) -> u32

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

pub fn android_soc_model(&self) -> &str

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

Trait Implementations

impl Clone for SystemInfo

fn clone(&self) -> SystemInfo

Returns a duplicate 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<(), Error>

Formats the value using the given formatter.

impl Default for SystemInfo

fn default() -> SystemInfo

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(&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 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.
