Description of the shallow layout of a variant

Trait Implementations

impl<'a, F: Clone + Deref<Target = [Field<'a>]>> Clone for Variant<'a, F>

fn clone(&self) -> Variant<'a, F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, F: Debug + Deref<Target = [Field<'a>]>> Debug for Variant<'a, F>

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

Formats the value using the given formatter.

impl<'de: 'a, 'a, F> Deserialize<'de> for Variant<'a, F>

where F: Deserialize<'de> + Deref<Target = [Field<'a>]>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a, F: Hash + Deref<Target = [Field<'a>]>> Hash for Variant<'a, F>

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, F: Deref<Target = [Field<'a>]> + Ord> Ord for Variant<'a, F>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<'a, F: PartialEq + Deref<Target = [Field<'a>]>> PartialEq for Variant<'a, F>

fn eq(&self, other: &Variant<'a, F>) -> 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.

impl<'a, F: Deref<Target = [Field<'a>]> + PartialOrd> PartialOrd for Variant<'a, F>

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'a, F> Serialize for Variant<'a, F>

where F: Serialize + Deref<Target = [Field<'a>]>,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a, F: Copy + Deref<Target = [Field<'a>]>> Copy for Variant<'a, F>

impl<'a, F: Eq + Deref<Target = [Field<'a>]>> Eq for Variant<'a, F>

impl<'a, F: Deref<Target = [Field<'a>]>> StructuralEq for Variant<'a, F>

impl<'a, F: Deref<Target = [Field<'a>]>> StructuralPartialEq for Variant<'a, F>
