Module maitake_sync::spin::once

Cells storing a value which must be initialized prior to use.

This module provides:

• InitOnce: a cell storing a MaybeUninit value which must be manually initialized prior to use.
• Lazy: an InitOnce cell coupled with an initializer function. The Lazy cell ensures the initializer is called to initialize the value the first time it is accessed.

Structs

• InitOnce
  A cell which may be initialized a single time after it is created.
• Lazy
  A cell which will be lazily initialized by the provided function the first time it is accessed.
• TryInitError
  Errors returned by InitOnce::try_init.
