Implementations

impl LexicalEnvironment

pub fn new(global: Value) -> Self

pub fn push(&mut self, env: Environment)

pub fn pop(&mut self) -> Option<Environment>

pub fn environments(&self) -> impl Iterator<Item = Environment>

pub fn get_global_object(&self) -> Option<Value>

pub fn create_mutable_binding(
    &mut self,
    name: String,
    deletion: bool,
    scope: VariableScope
)

pub fn create_immutable_binding(
    &mut self,
    name: String,
    deletion: bool,
    scope: VariableScope
) -> bool

pub fn set_mutable_binding(&mut self, name: &str, value: Value, strict: bool)

pub fn initialize_binding(&mut self, name: &str, value: Value)

pub fn get_current_environment_ref(&self) -> &Environment

get_current_environment_ref is used when you only need to borrow the environment (you only need to add a new variable binding, or you want to fetch a value)

pub fn get_current_environment(&mut self) -> &mut Environment

When neededing to clone an environment (linking it with another environnment) cloning is more suited. The GC will remove the env once nothing is linking to it anymore

pub fn has_binding(&self, name: &str) -> bool

pub fn get_binding_value(&self, name: &str) -> Value
