    pub jank_severity_type: Option<i32>,
}

Indicates the start of actual timeline slice for SurfaceFrames. 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 the app for its work. Can be shared between multiple layers of the same app (example: pip mode).

display_frame_token: Option<i64>

The corresponding DisplayFrame token is required to link the App’s work with SurfaceFlinger’s work. Many SurfaceFrames can be mapped to a single DisplayFrame. this.display_frame_token = DisplayFrame.token

pid: Option<i32>

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

layer_name: Option<String>

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>

is_buffer: Option<bool>

jank_severity_type: Option<i32>

Trait Implementations

impl Clone for ActualSurfaceFrameStart

fn clone(&self) -> ActualSurfaceFrameStart

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ActualSurfaceFrameStart

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

Formats the value using the given formatter.

impl Default for ActualSurfaceFrameStart

fn default() -> Self

Returns the “default value” for a type.

impl Message for ActualSurfaceFrameStart

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,

impl PartialEq for ActualSurfaceFrameStart

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