EmptyCount

vstd_extra::resource::ghost_resource::count_auth

Struct EmptyCount 

Source 
pub struct EmptyCount<T, const TOTAL: usize = 2> { /* private fields */ }

Implementations§

Source§

impl<T, const TOTAL: usize> EmptyCount<T, TOTAL>

Source

pub closed spec fn id(self) -> Loc

Returns the unique identifier.

Source

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

requires
TOTAL > 0,

Allocates a new EmptyCount, the id is arbitrary.

Source

pub proof fn put_resource(tracked self, tracked resource: T) -> tracked frac : Count<T, TOTAL>

ensures
frac.id() == self.id(),
frac.resource() == resource,
frac.frac() == TOTAL,
frac.has_authority(),

Puts a resource into the EmptyCount, returning a Count with the same id and the full fraction.
