Expand description

Unique authority to perform a one-shot transition.

Implementations§

Source§

impl OneShotPending

Source

pub proof fn alloc() -> tracked result : Self

Creates a pending one-shot transition at a fresh resource location.

Source

pub closed spec fn id(self) -> Loc

The resource location of this one-shot transition.

Source

pub proof fn set(tracked self) -> tracked result : OneShotSet

ensures
result.id() == self.id(),

Consumes the unique pending authority and marks the transition as set.

Source

pub proof fn incompatible(tracked &self, tracked set: &OneShotSet)

ensures
self.id() != set.id(),

A pending authority cannot coexist with set knowledge at the same location.
