Trait Implementations

impl Clone for CallStack

fn clone(&self) -> CallStack

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Context for CallStack

fn assign_lazy(&mut self, to: Expr, from: Expr) -> EvalResult

fn assign(&mut self, to: Expr, from: Obj) -> EvalResult

fn env(&self) -> Rc<Environment>

fn eval_call_mut(&mut self, expr: Expr) -> EvalResult

fn eval_call(&mut self, expr: Expr) -> EvalResult

fn eval(&mut self, expr: Expr) -> EvalResult

fn eval_and_finalize(&mut self, expr: Expr) -> EvalResult

fn eval_mut(&mut self, expr: Expr) -> EvalResult

fn get(&mut self, name: String) -> EvalResult

fn get_mut(&mut self, name: String) -> EvalResult

fn get_ellipsis(&mut self) -> EvalResult

fn eval_in(&mut self, expr: Expr, env: Rc<Environment>) -> EvalResult

impl Debug for CallStack

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CallStack

fn default() -> Self

Returns the “default value” for a type.

impl Display for CallStack

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Session> for CallStack

fn from(value: Session) -> Self

Converts to this type from the input type.

impl PartialEq for CallStack

fn eq(&self, other: &CallStack) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
