ArcRef

ostd::sync::non_null

Struct ArcRef

pub struct ArcRef<'a, T: 'static> { /* private fields */ }

Expand description

A type that represents &'a Arc<T>.

Implementations§

impl<'a, T> ArcRef<'a, T>

pub open spec fn ptr(self) -> *const T

{ arc_pointer_spec(*self.deref_as_arc_spec()) }

pub closed spec fn deref_as_arc_spec(&self) -> &Arc<T>

pub broadcast proof fn arcref_deref_spec_eq(self)

ensures

#[trigger] self.deref_as_arc_spec() == #[trigger] self.deref_spec(),

A workaround that Verus does not support implementing spec for Deref trait yet.

impl<'a, T> ArcRef<'a, T>

pub exec fn deref_target(&self) -> ret : &'a T

ensures

*ret == *(self.deref_as_arc_spec()),

Dereferences self to get a reference to T with the lifetime 'a. VERUS LIMITATION: The code includes a cast from &T to *const T, which is not specified yet in Verus. This is also a nontrivial use case that extends the lifetime of the reference.
