Struct Tuple 

pub struct Tuple<T>(/* private fields */);

This type is used to store anything shaped like an espy tuple.

This includes:

• Tuple<Value> (an espy tuple)
• Tuple<StaticValue> (an espy tuple with a static lifetime)
• Tuple<ComplexType> (the type of an espy tuple)

It is either a “numeric” tuple (indexed only by order) or a “named” tuple (indexed by both order and name).

Trait Implementations

impl<T: Clone> Clone for Tuple<T>

fn clone(&self) -> Tuple<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Tuple<T>

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

Formats the value using the given formatter.

impl<const N: usize, K: Into<Rc<str>>, T> From<[(K, T); N]> for Tuple<T>

fn from(value: [(K, T); N]) -> Self

Converts to this type from the input type.

impl<const N: usize, T> From<[T; N]> for Tuple<T>

fn from(value: [T; N]) -> Self

Converts to this type from the input type.

impl<T> From<Rc<[(Rc<str>, T)]>> for Tuple<T>

fn from(value: Rc<[(Rc<str>, T)]>) -> Self

Converts to this type from the input type.

impl<T> From<Rc<[T]>> for Tuple<T>

fn from(value: Rc<[T]>) -> Self

Converts to this type from the input type.

impl<'host, T: Borrow<Tuple<StaticValue>>> From<T> for Tuple<Value<'host>>

fn from(value: T) -> Self

Converts to this type from the input type.

impl From<Tuple<ComplexType>> for ComplexType

fn from(value: Tuple<ComplexType>) -> Self

Converts to this type from the input type.

impl From<Tuple<ComplexType>> for Tuple<Value<'_>>

fn from(tuple: Tuple<ComplexType>) -> Self

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for Tuple<T>

fn eq(&self, other: &Tuple<T>) -> 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.

type Error = Error

The type returned in the event of a conversion error.

fn try_from(tuple: Tuple<Value<'host>>) -> Result<Self, Self::Error>

Performs the conversion.

impl<'host> TryFrom<Tuple<Value<'host>>> for Tuple<Function<'host>>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(tuple: Tuple<Value<'host>>) -> Result<Self, Self::Error>

Performs the conversion.

impl<'host> TryFrom<Value<'host>> for Tuple<Value<'host>>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: Value<'host>) -> Result<Self, Self::Error>

Performs the conversion.
