Struct Context

pub struct Context<T, U> { /* private fields */ }

Struct for interacting with variable store and function store.

Implementations

impl<T, U> Context<T, U>

pub const fn new(variable_store: T, function_store: U) -> Self

Creates new Context.

Trait Implementations

impl<T: Clone, U: Clone> Clone for Context<T, U>

fn clone(&self) -> Context<T, U>
