Struct Tuple 

pub struct Tuple {
    pub bindings: Vec<(String, TupleValue)>,
}

A named-tuple value. Subset of the polydat Value set that is the strategy layer’s currency; the runtime walker converts Values to it before apply and maps results back. For the strategy module in isolation, this lightweight type lets tests run without pulling in the broader runtime.

Fields

bindings: Vec<(String, TupleValue)>

The tuple’s (name, value) pairs, in shape order.

Implementations

impl Tuple

pub fn new() -> Self

An empty tuple.

pub fn with<K: Into<String>>(self, key: K, value: TupleValue) -> Self

The tuple with one more binding.

Trait Implementations

impl Clone for Tuple

fn clone(&self) -> Tuple

impl Debug for Tuple

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

impl Default for Tuple

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Tuple

fn eq(&self, other: &Tuple) -> bool

Equality operator ==.

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