Struct JobContext 

#[non_exhaustive]
pub struct JobContext {
    pub state: AppState,
    pub attempt: u32,
    pub id: i64,
    pub batch_id: Option<i64>,
}

What a job gets when it runs.

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.

state: AppState

The app’s state (database, mailer, queue…).

attempt: u32

1 on the first try.

id: i64

The job’s id (0 for AppState::dispatch_sync).

batch_id: Option<i64>

The batch it belongs to, or, for a batch’s then/catch/finally job, the batch it follows (read it with queue.batch_status).
