Struct TerminalSlot 

pub struct TerminalSlot { /* private fields */ }

The operation’s single terminal slot.

TerminalSlot::commit succeeds once and refuses every later attempt, including an identical one. That is the exactly-once invariant of §7.12 as an API: no caller can double-commit by forgetting to check first, and a resumed operation that re-derives its terminal is told so instead of emitting a second one.
