Enum Item

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

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.
