//! \brief Tracks whether data are initialized.
//!
//! Objects of this type track whether the data they’re guarding are
//! initialized. The three possible states are uninitialized (the initial
//! state), initializing, and valid. As the guarded data are initialized, an
//! InitializationState object will normally transition through these three
//! states. A fourth state corresponds to the destruction of objects of this
//! type, making it less likely that a use-after-free of an InitializationState
//! object will appear in the valid state.
//!
//! If the only purpose for tracking the initialization state of guarded data is
//! to DCHECK when the object is in an unexpected state, use
//! InitializationStateDcheck instead.
