Implementations

impl Interpreter

pub fn new() -> Self

pub fn execute(&mut self, file: &SourceFile) -> Result<Value, RuntimeError>

Execute a source file

pub fn evaluate(&mut self, expr: &Expr) -> Result<Value, RuntimeError>

Evaluate an expression

pub fn call_function( &mut self, func: &Function, args: Vec<Value>, ) -> Result<Value, RuntimeError>

pub fn await_value(&mut self, value: Value) -> Result<Value, RuntimeError>

Await a value - if it’s a future, resolve it; otherwise return as-is

pub fn make_future_immediate(&self, value: Value) -> Value

Create a new future from a value

pub fn make_future_lazy(&self, func: Rc<Function>, args: Vec<Value>) -> Value

Create a pending future with lazy computation

pub fn make_future_timer(&self, duration: Duration) -> Value

Create a timer future

Trait Implementations

impl Default for Interpreter

fn default() -> Self

Returns the “default value” for a type.
