Struct Event 

pub struct Event {
    pub seq: u64,
    pub at: SystemTime,
    pub timeout_ms: Option<u32>,
    pub delay_ms: Option<u32>,
    pub reason: Option<Arc<str>>,
    pub attempt: Option<u32>,
    pub task: Option<Arc<str>>,
    pub kind: EventKind,
    pub backoff_source: Option<BackoffSource>,
    /* private fields */
}

Runtime event with optional metadata.

• seq: monotonic global sequence for ordering
• at: wall-clock timestamp (for logs)
• other optional fields are set depending on the EventKind

Fields

seq: u64

Globally unique, monotonically increasing sequence number.

at: SystemTime

Wall-clock timestamp.

timeout_ms: Option<u32>

Task timeout in milliseconds (compact).

delay_ms: Option<u32>

Backoff delay before next attempt in milliseconds (compact).

reason: Option<Arc<str>>

Human-readable reason (errors, overflow details, etc.).

attempt: Option<u32>

Attempt count (starting from 1).

task: Option<Arc<str>>

Name of the task, if applicable.

kind: EventKind

Event classification.

backoff_source: Option<BackoffSource>

Source for backoff scheduling (success vs failure).

Implementations

impl Event

pub fn new(kind: EventKind) -> Self

Creates a new event of the given kind with current timestamp and next sequence number.

pub fn with_reason(self, reason: impl Into<Arc<str>>) -> Self

Attaches a human-readable reason.

pub fn with_task(self, task: impl Into<Arc<str>>) -> Self

Attaches a task name.

pub fn with_timeout(self, d: Duration) -> Self

Attaches a timeout duration (stored as milliseconds).

pub fn with_delay(self, d: Duration) -> Self

Attaches a backoff delay (stored as milliseconds).

pub fn with_attempt(self, n: u32) -> Self

Attaches an attempt count.

pub fn with_backoff_success(self) -> Self

Marks that this backoff comes from a successful attempt.

pub fn with_backoff_failure(self) -> Self

Marks that this backoff comes from a failed attempt.

pub fn subscriber_overflow( subscriber: &'static str, reason: &'static str, ) -> Self

Creates a subscriber overflow event.

pub fn subscriber_panicked(subscriber: &'static str, info: String) -> Self

Creates a subscriber panic event.

pub fn is_subscriber_overflow(&self) -> bool

pub fn is_subscriber_panic(&self) -> bool

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a duplicate of the value.

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