Implementations

impl<A: ErasablePtr, B: ErasablePtr, C: ErasablePtr, D: ErasablePtr> Enum4<A, B, C, D>

pub fn pack(self, builder: Builder4<A, B, C, D>) -> Union4<A, B, C, D>

Pack this loose enum into a pointer union.

pub fn try_pack(self) -> Result<Union4<A, B, C, D>, Self>

Pack this loose enum into a pointer union.

pub unsafe fn pack_unchecked(self) -> Union4<A, B, C, D>

Pack this loose enum into a pointer union.

Safety

The pointer packed must be properly aligned. Note that only the actually packed pointer is restricted, not any other pointer type involved in this definition.

Trait Implementations

impl<A: Clone, B: Clone, C: Clone, D: Clone> Clone for Enum4<A, B, C, D>

fn clone(&self) -> Enum4<A, B, C, D>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A: Debug, B: Debug, C: Debug, D: Debug> Debug for Enum4<A, B, C, D>

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

Formats the value using the given formatter.

impl<A: Hash, B: Hash, C: Hash, D: Hash> Hash for Enum4<A, B, C, D>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<A: PartialEq, B: PartialEq, C: PartialEq, D: PartialEq> PartialEq<Enum4<A, B, C, D>> for Enum4<A, B, C, D>

fn eq(&self, other: &Enum4<A, B, C, D>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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