Struct ExpectedDisplayFrameStart

pub struct ExpectedDisplayFrameStart {
    pub cookie: Option<i64>,
    pub token: Option<i64>,
    pub pid: Option<i32>,
}

Indicates the start of expected timeline slice for DisplayFrames.

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.

Implementations

impl ExpectedDisplayFrameStart

pub fn cookie(&self) -> i64

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

pub fn token(&self) -> i64

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

pub fn pid(&self) -> i32

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

Trait Implementations

impl Clone for ExpectedDisplayFrameStart

fn clone(&self) -> ExpectedDisplayFrameStart

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExpectedDisplayFrameStart

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

impl Default for ExpectedDisplayFrameStart

fn default() -> Self

Returns the “default value” for a type.

impl Message for ExpectedDisplayFrameStart

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,

Encodes the message to a newly allocated buffer.

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,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ExpectedDisplayFrameStart

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