Struct Trace 

#[non_exhaustive]
pub struct Trace {
    pub processes: Vec<ProcessTrace>,
}

Represents a recorded trace.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

processes: Vec<ProcessTrace>

Traced app processes.

Implementations

impl Trace

pub fn read_chrome_trace(json_path: impl AsRef<Path>) -> Result<Self>

Read and parse a Chrome JSON Array format trace.

See parse_chrome_trace for more details.

pub fn parse_chrome_trace(json: &str) -> Result<Self>

Parse a Chrome JSON Array format trace.

Only supports the “phases” emitted by tracing-chrome in TraceStyle::Threaded mode, those are B, E, i, M for M only supports thread_name metadata. Also parses the custom messages that define the process name and start timestamp as defined by the zng::app::trace_recorder documentation.

pub fn to_chrome_trace(&self) -> Txt

Convert the trace to Chrome JSON Array format.

pub fn write_chrome_trace(&self, json_path: impl AsRef<Path>) -> Result<()>

Convert and write the trace to Chrome JSON Array format.

pub fn merge(&mut self, other: Self)

Merge other into this.

pub fn sort(&mut self)

Sort processes processes and threads by start time then name, events by instant and spans by start.

Trait Implementations

impl Clone for Trace

fn clone(&self) -> Trace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Trace

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

Formats the value using the given formatter.
