Struct SchedulingContext 

pub struct SchedulingContext {
    pub current_time_ms: i64,
    pub remaining_work: HashMap<String, i64>,
    pub next_queue_length: HashMap<String, usize>,
    pub resource_utilization: HashMap<String, f64>,
    pub arrival_times: HashMap<String, i64>,
    pub average_processing_time: Option<f64>,
}

Runtime scheduling state passed to dispatching rules.

Contains the current simulation clock, remaining work estimates, resource utilization, and arrival times needed by context-aware rules.

All times are in milliseconds relative to the scheduling epoch (t=0).

Fields

current_time_ms: i64

Current simulation time (ms).

remaining_work: HashMap<String, i64>

Remaining processing work per task (task_id → ms).

next_queue_length: HashMap<String, usize>

Queue length at next resource per task.

resource_utilization: HashMap<String, f64>

Current resource utilization (resource_id → 0.0..1.0).

arrival_times: HashMap<String, i64>

Task arrival times (task_id → ms).

average_processing_time: Option<f64>

Average processing time across all tasks (for ATC normalization).

Implementations
