Struct TypeDefTuple

pub struct TypeDefTuple<T: Form = MetaForm> {
    pub fields: Vec<T::Type>,
}

A type to refer to tuple types.

Fields

fields: Vec<T::Type>

The types of the tuple fields.

Implementations

impl TypeDefTuple

pub fn new<T>(type_params: T) -> Self

where T: IntoIterator<Item = MetaType>,

Creates a new tuple type definition from the given types.

pub fn unit() -> Self

Creates a new unit tuple to represent the unit type, ().

impl TypeDefTuple<PortableForm>

pub fn new_portable<I>(type_params: I) -> Self

where I: IntoIterator<Item = <PortableForm as Form>::Type>,

Creates a new custom type definition from the given types.

impl<T> TypeDefTuple<T>

where T: Form,

pub fn fields(&self) -> &[T::Type]

👎Deprecated since 2.5.0: Prefer to access the fields directly; this getter will be removed in the next major version

Returns the types of the tuple fields.

impl<F: Form> From<TypeDefTuple<F>> for Type<F>

fn from(item: TypeDefTuple<F>) -> Self

Converts to this type from the input type.

impl<F: Form> From<TypeDefTuple<F>> for TypeDef<F>

fn from(x: TypeDefTuple<F>) -> Self

Converts to this type from the input type.

impl IntoPortable for TypeDefTuple

type Output = TypeDefTuple<PortableForm>

The portable version of Self.

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

Convert self to the portable form by using the registry for caching.

impl<T: Ord + Form> Ord for TypeDefTuple<T>

where T::Type: Ord,

fn cmp(&self, other: &TypeDefTuple<T>) -> Ordering

This method returns an Ordering between self and other.

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