Enum shroom::primitive::Primitive

pub enum Primitive {
    Int(i64),
    Float(f64),
    Bool(bool),
    Str(String),
}

Emulates a simple dynamic type system for expression evaluation. Contains a single value of type i64, f64, bool or String.

Examples

let x = Primitive::Int(2);
let y = Primitive::Int(3);

assert_eq!(x.add(&y).unwrap().unwrap_int(), 5);

Variants

Int(i64)Float(f64)Bool(bool)Str(String)
