Struct Scope 

pub struct Scope {
    pub inst: Option<Rc<RefCell<RecInst>>>,
    pub locals: Rc<HashMap<String, Value>>,
    pub root_name: String,
    pub menv: Option<Rc<Env>>,
}

locals: Rc<HashMap<String, Value>>

the local variables

root_name: String

the root

menv: Option<Rc<Env>>

the module environment

Implementations

impl Scope

pub fn new(root_name: &str, menv: Option<Rc<Env>>) -> Scope

A scope at a root.

pub fn with_locals(&self, locals: HashMap<String, Value>) -> Scope

The scope with local variables.

pub fn with_inst(&self, inst: Option<Rc<RefCell<RecInst>>>) -> Scope

The scope inside an instance.

pub fn with_menv(&self, menv: Option<Rc<Env>>) -> Scope

The scope in a module environment.
