Enum Value 

pub enum Value {
    Boolean(bool),
    String(String),
    Number(f64),
    Array(Vec<Value>),
}

A Wrapper for the four different possible variable types.

Variants

Boolean(bool)

String(String)

Number(f64)

Array(Vec<Value>)

Implementations

impl Value

pub fn div_int(self, rhs: Self) -> Result<Self>

Integer division between two operands. Returns the whole number quotient, discarding any fractional part.

Examples

use slac::Value;

let a = Value::Number(10.0);
let b = Value::Number(3.0);

assert_eq!(Ok(Value::Number(3.0)), a.div_int(b));

Errors

Returns Error::InvalidBinaryOperator if any side of the operator is not a Number.

pub fn len(&self) -> usize

Returns the length of a String or Array Value. Boolean and Number have a length of 0.

pub fn is_empty(&self) -> bool

Checks if the value is equal to the result of Value::empty().

pub fn empty(&self) -> Self

Returns an new empty Value of the same type as the callee.

• Value::Boolean -> false
• Value::String -> ''
• Value::Number -> 0
• Value::Array -> []

pub fn as_bool(&self) -> bool

Returns the boolean representation of the Value. Returns Booleans as is. Other Value kinds are based on if the contained value is not Value::is_empty().
