Struct Trace 

pub struct Trace {
    pub events: Vec<PollEvent>,
    pub start: Instant,
}

Collected trace from a TracedFuture.

A Trace holds the recorded events plus a reference Instant used to compute event offsets. The reference instant is not serialized; when a Trace is deserialized the start field is reset to the deserialization time and only the per-event offset values are authoritative.

Examples

use async_reify::Trace;

let trace = Trace::new();
assert!(trace.events.is_empty());

Fields

events: Vec<PollEvent>

All poll events in order.

start: Instant

Reference instant against which each event’s offset was measured. Not serialized: only the offsets persist across (de)serialization.

Implementations

impl Trace

pub fn new() -> Self

Construct an empty trace anchored at the current instant.

Examples

use async_reify::Trace;

let t = Trace::new();
assert!(t.events.is_empty());

pub fn shared() -> Arc<Mutex<Trace>>

Return a fresh shared, mutex-protected trace suitable for use with LabeledFuture.

Examples

use async_reify::Trace;

let shared = Trace::shared();
assert!(shared.lock().unwrap().events.is_empty());

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.

impl Default for Trace

fn default() -> Self

Returns the “default value” for a type.
