Enum MailboxFullReason 

pub enum MailboxFullReason {
    MessageLimit,
    ByteLimit,
}

Which of a mailbox’s two bounds refused a hop.

Reported so an operator can tell “this flow is not draining its inbox” (Self::MessageLimit) from “this flow is being sent payloads too large for its budget” (Self::ByteLimit) without instrumenting the sender. Those have different fixes: raise capacity / speed up the receiver versus raise the byte budget / shrink the payload.

Variants

MessageLimit

MailboxCapacity hops are already queued.

ByteLimit

Accepting the hop would exceed the MailboxBytes budget. Also reported when a single hop is larger than the entire budget, which no eviction policy can make room for.
