pub struct Vacancy;

Represents a vacant slot in a certain map.

Trait Implementations

impl Clone for Vacancy

fn clone(&self) -> Vacancy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Vacancy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Vacancy

fn default() -> Vacancy

Returns the “default value” for a type.

impl MaybeAvailable for Vacancy

unsafe fn do_maybe_ref<T>(_data: &MaybeUninit<T>) -> Option<&T>

Safety

unsafe fn do_maybe_mut<T>(_data: &mut MaybeUninit<T>) -> Option<&mut T>

Safety

unsafe fn do_set<T>(data: &mut MaybeUninit<T>, value: T)

Safety

unsafe fn do_drop<T>(_data: &mut MaybeUninit<T>)

Safety

unsafe fn do_clone<T: Clone>(_data: &MaybeUninit<T>) -> MaybeUninit<T>

Safety

unsafe fn do_debug<T: Debug>( _data: &MaybeUninit<T>, f: &mut Formatter<'_>, ) -> Result

Safety

impl PartialEq for Vacancy

fn eq(&self, other: &Vacancy) -> 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.
