[−][src]Struct rw_lease::RWLease

pub struct RWLease<T, A = AtomicUsize> where
    A: AtomicInt,
    A::Prim: AddSign,  { /* fields omitted */ }

An RWLock, but:

  • Choose your atomic unsigned integer for storage:
    • We will steal the high bit for the writer.
    • We will count readers on the remaining bits.
  • Bring your own synchronisation primitive:
    • No looping
  • Writers wait for a lack of readers before assuming Write access.
