Struct Value

pub struct Value<'p> { /* private fields */ }

A fully evaluated value.

Each instance of Value are tied to a Program instance. Instances of this type will only be valid as long as the Program they came from has not been dropped.

Implementations

impl<'p> Value<'p>

pub fn null() -> Self

Creates a null value.

The returned Value will not be tied to any specific Program instance.

Creates a boolean value.

The returned Value will not be tied to any specific Program instance.

pub fn number(value: f64) -> Self

Creates a numberic value.

The returned Value will not be tied to any specific Program instance.

pub fn string(s: &str) -> Self

Creates a string value.

The returned Value will not be tied to any specific Program instance.
