Enum ProcessRole 

pub enum ProcessRole {
    Combined,
    Web,
    Worker,
}

Process role: which slice of the framework runtime this replica runs.

The same binary can be deployed under different roles so a fleet can scale its HTTP tier independently of its background-work tier. The role is chosen by config (role = "...") or the AUTUMN_ROLE env var only — application code never changes. The default, Combined, preserves today’s single-process behavior exactly.

• Combined: serves HTTP and runs job workers
  • the cron scheduler (default).
• Web: serves HTTP and can still enqueue jobs, but runs no #[job] worker loops and no #[scheduled]/cron scheduler.
• Worker: runs job workers + the cron scheduler and does not serve user routes, but still binds the HTTP listener to serve only the liveness/readiness probes and the actuator (so orchestrators can supervise it and /actuator/jobs works).

Variants

Combined

Serve HTTP and run background workers + scheduler (default; unchanged single-process behavior).

Web

Serve HTTP (and enqueue jobs) only — no worker loops, no scheduler.

Worker

Run workers + scheduler only — probe/actuator HTTP only, no user routes.

Implementations

impl ProcessRole

pub fn from_env_value(value: &str) -> Option<Self>

Parse an environment variable / flag value for process-role selection.

Accepts (case-insensitive, trimmed): combined/all, web/server/ http, worker/jobs. Returns None for anything else so callers can warn and keep the default.

pub const fn as_str(self) -> &'static str

Stable lowercase identifier for the role (round-trips from_env_value).

pub const fn serves_http(self) -> bool

Whether this role serves user HTTP routes (Combined or Web).

pub const fn runs_workers(self) -> bool

Whether this role runs background job workers and the cron scheduler (Combined or Worker).
