Struct Marc 

pub struct Marc<T> { /* private fields */ }

Atomic counted wrapper that updates a nonce counter on every mutable access of the inner content in an inner mutable container such as an RwLock or Mutex. It’s PartialEq behavior is reduced to comparing the memory location and counter index. For the potentially expensive true inner equality comparison, look for the implementation of inner_eq.

impl<T: PartialEq> InnerEq<T> for Marc<RwLock<T>>

fn inner_eq(&self, other: &Self) -> bool

Compare the equality of a wrapped type.

impl<T> PartialEq for Marc<T>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.
