Struct FrameTimelineEvent 

pub struct FrameTimelineEvent {
    pub event: Option<Event>,
}

Generated by SurfaceFlinger’s FrameTimeline (go/adaptive-scheduling-fr). Used in comparing the expected timeline of a frame to the actual timeline. Key terms: 1) DisplayFrame - represents SurfaceFlinger’s work on a frame(composited) 2) SurfaceFrame - represents App’s work on its frame 3) Timeline = start to end of a component’s(app/SF) work on a frame. SurfaceFlinger composites frames from many apps together, so One DisplayFrame can map to N SurfaceFrame(s) This relationship can be reconstructed by using DisplayFrame.token = SurfaceFrame.display_frame_token

Fields

event: Option<Event>

Trait Implementations

impl Clone for FrameTimelineEvent

fn clone(&self) -> FrameTimelineEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameTimelineEvent

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

Formats the value using the given formatter.

impl Default for FrameTimelineEvent

fn default() -> FrameTimelineEvent

Returns the “default value” for a type.

impl Message for FrameTimelineEvent

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 FrameTimelineEvent

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