Struct DepTaskNode 

#[non_exhaustive]
pub struct DepTaskNode {
    pub id: TaskId,
    pub name: String,
    pub priority: i32,
    pub estimated_cost: f64,
    pub metadata: HashMap<String, String>,
}

A single node in a DependencyGraph.

Stores task metadata without any compute closure.

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.

id: TaskId

Unique identifier for this task.

name: String

Human-readable name.

priority: i32

Scheduling priority: higher value means execute first among ready tasks.

estimated_cost: f64

Estimated execution cost (arbitrary units, used for critical-path analysis).

metadata: HashMap<String, String>

Arbitrary key-value metadata for application-level annotations.
