Implementations

impl<T0: 'static, T1: 'static, T2: 'static, T3: 'static> Variant4<T0, T1, T2, T3>

Trait Implementations

impl<T0: Clone, T1: Clone, T2: Clone, T3: Clone> Clone for Variant4<T0, T1, T2, T3>

fn clone(&self) -> Variant4<T0, T1, T2, T3>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T0: Debug, T1: Debug, T2: Debug, T3: Debug> Debug for Variant4<T0, T1, T2, T3>

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

Formats the value using the given formatter.

impl<T0: Default, T1, T2, T3> Default for Variant4<T0, T1, T2, T3>

fn default() -> Self

Returns the “default value” for a type.

impl<T0: Eq, T1: Eq, T2: Eq, T3: Eq> Eq for Variant4<T0, T1, T2, T3>

impl<T0: Hash, T1: Hash, T2: Hash, T3: Hash> Hash for Variant4<T0, T1, T2, T3>

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<T0: PartialEq, T1: PartialEq, T2: PartialEq, T3: PartialEq> PartialEq for Variant4<T0, T1, T2, T3>

fn eq(&self, other: &Variant4<T0, T1, T2, T3>) -> 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.
