Struct PriorityEntry 

pub struct PriorityEntry {
    pub task_id: String,
    pub priority: PriorityLevel,
    pub base_priority: PriorityLevel,
    pub deadline_secs: u64,
    pub submitted_secs: u64,
    pub age_count: u32,
    /* private fields */
}

An entry in the priority queue.

Fields

task_id: String

Task identifier.

priority: PriorityLevel

Current effective priority.

base_priority: PriorityLevel

Original priority before any aging.

deadline_secs: u64

Optional deadline (seconds since epoch; 0 = none).

submitted_secs: u64

Submission timestamp (seconds since epoch).

age_count: u32

Number of times this entry has been aged.

Implementations

impl PriorityEntry

pub fn new( task_id: impl Into<String>, priority: PriorityLevel, submitted_secs: u64, insertion_order: u64, ) -> Self

Create a new priority entry.

pub fn with_deadline(self, deadline_secs: u64) -> Self

Set a deadline.

pub fn has_deadline(&self) -> bool

Return true if this entry has a deadline.

pub fn is_overdue(&self, now_secs: u64) -> bool

Check whether the deadline has passed relative to now_secs.

pub fn wait_time(&self, now_secs: u64) -> u64

Return the time this entry has been waiting (in seconds).
