Struct scale_info::TypeDefVariant

pub struct TypeDefVariant<F: Form = MetaForm> { /* fields omitted */ }

A Enum type (consisting of variants).

Examples

A Rust enum, aka tagged union.

enum MyEnum {
    RustAllowsForClikeVariants,
    AndAlsoForTupleStructs(i32, bool),
    OrStructs {
        with: i32,
        named: bool,
        fields: [u8; 32],
    },
    ItIsntPossibleToSetADiscriminantThough,
}

A C-like enum type.

enum Days {
    Monday,
    Tuesday,
    Wednesday,
    Thursday = 42, // Also allows to manually set the discriminant!
    Friday,
    Saturday,
    Sunday,
}

An empty enum (for marker purposes)

enum JustAMarker {}

impl IntoCompact for TypeDefVariant

type Output = TypeDefVariant<CompactForm>

The compact version of Self.

fn into_compact(self, registry: &mut Registry) -> Self::Output

Compacts self by using the registry for caching and compaction.

impl<F: Ord + Form> Ord for TypeDefVariant<F>

fn cmp(&self, other: &TypeDefVariant<F>) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl<F: PartialEq + Form> PartialEq<TypeDefVariant<F>> for TypeDefVariant<F>

fn eq(&self, other: &TypeDefVariant<F>) -> bool

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

fn ne(&self, other: &TypeDefVariant<F>) -> bool

This method tests for !=.

impl<F: PartialOrd + Form> PartialOrd<TypeDefVariant<F>> for TypeDefVariant<F>

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

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

fn lt(&self, other: &TypeDefVariant<F>) -> bool

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

fn le(&self, other: &TypeDefVariant<F>) -> bool

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

fn gt(&self, other: &TypeDefVariant<F>) -> bool

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

fn ge(&self, other: &TypeDefVariant<F>) -> bool

impl<F: Form> Serialize for TypeDefVariant<F> where
    F::TypeId: Serialize, 

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