Enum Item

pub enum Item<Op, Val = Value>
where
    Op: Debug,
    Val: Debug,
{
    Operator(Op),
    Value(Val),
}

An Item is each one of the entities that conform a Script.

In other words, a Script is no more than an array of Items in the likes of [Item<Op, Val>].

Ìtem does not implement any methods other than implementations of some traits from the core crate.

Variants

Operator(Op)

An operator code, either a variant of an user-defined enum containing different operator identifiers, or any of the ones found in the op_systems module.

Value(Val)

A value, either a variant of an user-defined enum representing a type system, or an instance of any of the variants of Value, i.e. Boolean, Float, Integer or String.

Trait Implementations

impl<Op, Val> Clone for Item<Op, Val>

where Op: Debug + Clone, Val: Debug + Clone,

fn clone(&self) -> Item<Op, Val>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Op, Val> Debug for Item<Op, Val>

where Op: Debug + Debug, Val: Debug + Debug,

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

Formats the value using the given formatter.

impl<Op, Val> PartialEq for Item<Op, Val>

where Op: Debug + PartialEq, Val: Debug + PartialEq,

fn eq(&self, other: &Item<Op, Val>) -> 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.

impl<Op, Val> StructuralPartialEq for Item<Op, Val>

where Op: Debug, Val: Debug,
