Struct UiState

pub struct UiState {
    pub timeline_start_ts: Option<i64>,
    pub timeline_end_ts: Option<i64>,
    pub highlight_process: Option<HighlightProcess>,
}

Common state for UIs visualizing Perfetto traces. This message can be appended as a TracePacket by UIs to save the visible state (e.g. scroll position/zoom state) for future opening of the trace. Design doc: go/trace-ui-state.

Fields

timeline_start_ts: Option<i64>

The start and end bounds of the viewport of the UI in nanoseconds.

This is the absolute time associated to slices and other events in trace processor tables (i.e. the |ts| column of most tables)

timeline_end_ts: Option<i64>

highlight_process: Option<HighlightProcess>

Implementations

impl UiState

pub fn timeline_start_ts(&self) -> i64

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

pub fn timeline_end_ts(&self) -> i64

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

Trait Implementations

impl Clone for UiState

fn clone(&self) -> UiState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UiState

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

Formats the value using the given formatter.

impl Default for UiState

fn default() -> Self

Returns the “default value” for a type.

impl Message for UiState

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 UiState

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