Enum State 

#[repr(usize)]
enum State {
    Uninitialized = 0,
    Initializing = 1,
    Initialized = 2,
}

The current state of the OnceCell.

Variants

Uninitialized = 0

The OnceCell is uninitialized.

Initializing = 1

The OnceCell is being initialized.

Initialized = 2

The OnceCell is initialized.

Trait Implementations

impl Clone for State

fn clone(&self) -> State

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<State> for usize

fn from(val: State) -> Self

Converts to this type from the input type.

impl From<usize> for State

fn from(val: usize) -> Self

Converts to this type from the input type.

impl PartialEq for State

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

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

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for State

impl Eq for State

impl StructuralPartialEq for State
