Struct ExpectedSurfaceFrameStart

pub struct ExpectedSurfaceFrameStart {
    pub cookie: Option<i64>,
    pub token: Option<i64>,
    pub display_frame_token: Option<i64>,
    pub pid: Option<i32>,
    pub layer_name: Option<String>,
}

Indicates the start of expected timeline slice for SurfaceFrames.

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>

Implementations

impl ExpectedSurfaceFrameStart

pub fn token(&self) -> i64

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

pub fn display_frame_token(&self) -> i64

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

pub fn pid(&self) -> i32

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

pub fn layer_name(&self) -> &str

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

Trait Implementations

impl Clone for ExpectedSurfaceFrameStart

fn clone(&self) -> ExpectedSurfaceFrameStart

Returns a copy of the value.

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

impl Default for ExpectedSurfaceFrameStart

fn default() -> Self

Returns the “default value” for a type.

impl Message for ExpectedSurfaceFrameStart

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,

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,

impl PartialEq for ExpectedSurfaceFrameStart

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