Module conquer_once::spin

Synchronized one-time and lazy initialization primitives that use spin-locks in case of concurrent accesses under contention.

Type Definitions

• Lazy
  A type for lazy initialization of e.g. global static variables, which provides the same functionality as the lazy_static! macro.
• Once
  A synchronization primitive which can be used to run a one-time global initialization.
• OnceCell
  An interior mutability cell type which allows synchronized one-time initialization and read-only access exclusively after initialization.
