Struct Batch 

pub struct Batch {
    pub tag: Option<String>,
    pub deadline: Option<SystemTime>,
    pub ordering_key: Option<String>,
    pub max_attempts: Option<u32>,
    pub low_priority: bool,
    pub synchronize_collection: bool,
}

What a batch of deliveries shares: a tag to find them by, when to give up on the ones that have not gone through, and what they are sent in order with.

Fields

tag: Option<String>

Kept with each delivery, as tag in its payload, for the application to follow the batch by.

deadline: Option<SystemTime>

A delivery that has not gone through by then is given up on, reported to the failure handler with DeliveryFailure::deadline set. One that would next be tried after it is given up on at once.

ordering_key: Option<String>

Deliveries sent with the same key reach each inbox in the order they were queued: one waits until those before it to that inbox have gone through or been given up on. The key is typically the object an activity is about, so that its Delete cannot overtake its Create while the Create is being retried. Inboxes do not wait on each other.

max_attempts: Option<u32>

How many times each delivery is tried at most, when fewer than the retry policy allows: its backoff stays the policy’s.

low_priority: bool

Sent in DelivererConfig::low_priority’s lane, when there is one.

synchronize_collection: bool

Sent with a Collection-Synchronization header (FEP-8fcf), as Deliverer::collection_synchronization writes it for the sender and the inbox when the delivery is made.
