Struct LayersTraceFileProto

pub struct LayersTraceFileProto {
    pub magic_number: Option<u64>,
    pub entry: Vec<LayersSnapshotProto>,
    pub real_to_elapsed_time_offset_nanos: Option<u64>,
}

Message used by Winscope to process legacy trace files. Represents a file full of surface flinger trace entries. Encoded, it should start with 0x4c 0x59 0x52 0x54 0x52 0x41 0x43 0x45 (.LYRTRACE), such that they can be easily identified.

Fields

magic_number: Option<u64>

Must be the first field, set to value in MagicNumber

entry: Vec<LayersSnapshotProto>

real_to_elapsed_time_offset_nanos: Option<u64>

Offset between real-time clock and elapsed time clock in nanoseconds. Calculated as: systemTime(SYSTEM_TIME_REALTIME) - systemTime(SYSTEM_TIME_MONOTONIC)

Implementations

impl LayersTraceFileProto

pub fn magic_number(&self) -> u64

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

pub fn real_to_elapsed_time_offset_nanos(&self) -> u64

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

Trait Implementations

impl Clone for LayersTraceFileProto

fn clone(&self) -> LayersTraceFileProto

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LayersTraceFileProto

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

Formats the value using the given formatter.

impl Default for LayersTraceFileProto

fn default() -> Self

Returns the “default value” for a type.

impl Message for LayersTraceFileProto

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 LayersTraceFileProto

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