Struct SimpleContext 

pub struct SimpleContext { /* private fields */ }

A simple context that stores the variables in a hash map.

For those who don’t want to implement the Context trait, this is a simple implementation that can be used.

Implementations

impl SimpleContext

pub fn new(vars: HashMap<String, ExprValue>) -> Self

pub fn add_fn(&mut self, name: String, func: Box<dyn ExprFn>)
