}

Indicates the start of actual timeline slice for DisplayFrames. Also includes the jank information.

Fields

cookie: Option<i64>

Cookie used to correlate between the start and end messages of the same frame. Since all values except the ts are same for start and end, cookie helps in preventing redundant data transmission. The same cookie is used only by start and end messages of a single frame and is otherwise unique.

token: Option<i64>

Token received by SurfaceFlinger for its work this.token = SurfaceFrame.display_frame_token

pid: Option<i32>

Pid of SurfaceFlinger. Used in creating the timeline tracks (and slices) inside the SurfaceFlinger process group.

present_type: Option<i32>

on_time_finish: Option<bool>

gpu_composition: Option<bool>

jank_type: Option<i32>

A bitmask of JankType. More than one reason can be attributed to a janky frame.

prediction_type: Option<i32>

jank_severity_type: Option<i32>

present_delay_millis: Option<f32>

jank_severity_score: Option<f32>

jank_type_experimental: Option<i32>

experimental value for jank_type. Do not consider in jank analysis.

present_type_experimental: Option<i32>

experimental value for present_type. Do not consider in jank analysis.

Trait Implementations

impl Clone for ActualDisplayFrameStart

fn clone(&self) -> ActualDisplayFrameStart

Returns a duplicate of the value.

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

impl Default for ActualDisplayFrameStart

fn default() -> Self

Returns the “default value” for a type.

impl Message for ActualDisplayFrameStart

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>

impl PartialEq for ActualDisplayFrameStart

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