Struct scale_info::TypeDefComposite

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

A composite type, consisting of either named (struct) or unnamed (tuple struct) fields

Examples

A Rust struct with named fields.

struct Person {
    name: String,
    age_in_years: u8,
    friends: Vec<Person>,
}

A tuple struct with unnamed fields.

struct Color(u8, u8, u8);

A so-called unit struct

struct JustAMarker;

impl IntoCompact for TypeDefComposite

type Output = TypeDefComposite<CompactForm>

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

fn cmp(&self, other: &TypeDefComposite<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<TypeDefComposite<F>> for TypeDefComposite<F>

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

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

This method tests for !=.

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

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

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

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

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

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

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