Struct SharedReference 

Source 
pub struct SharedReference<'a, T>(/* private fields */);
Expand description

This is meant to be a replacement for &'a T that allows Verus to keep track of not just the T value but the pointer as well. It would be better to get rid of this and use normal reference types &'a T, but there are a lot of unsolved implementation questions. The existence of SharedReference<'a, T> is a stop-gap.

Implementations§

Source§

impl<'a, T> SharedReference<'a, T>

Source

pub uninterp fn value(self) -> T
