Struct SessionGuard 

pub struct SessionGuard<'a, V> { /* private fields */ }

A reference to a session variable of type V, returned by SessionExt::get and SessionExt::get_opt.

It borrows the session’s current snapshot through an arc_swap::Guard, so reads never take a lock or a full Arc clone. The guard is tied to the session borrow it was read from, so it is meant to be used on the stack rather than stored in a long-lived data structure (holding it pins an internal arc-swap slot, which can contend with concurrent writers). SessionGuard derefs to V, so it can be used wherever a &V is expected.
