TaskDescriptor

Struct TaskDescriptor 

Source
pub struct TaskDescriptor<F> {
    pub name: &'static str,
    pub restart: RestartPolicy,
    pub factory: F,
}
Expand description

Configuration passed to TaskSupervisor::spawn to describe a supervised task.

F must be Fn (not FnOnce) to support restarts: the factory is called once on initial spawn and once per restart attempt.

Fields§

§name: &'static str

Unique name for this task (e.g., "config-watcher", "scheduler-loop").

Names must be 'static — they are typically compile-time string literals. Spawning a task with a name that already exists aborts the prior instance.

§restart: RestartPolicy

Restart policy applied when the task exits unexpectedly.

§factory: F

Factory called to produce a new future. Must be Fn for restart support.
