pub struct RefValue { /* private fields */ }

Implementations

impl RefValue

pub fn create_method(&self, method_name: &str) -> Result<RefValue, String>

Creates a callable Method object from a RefValue and a given method name.

pub fn call_method(
    &self,
    name: &str,
    args: Vec<RefValue>
) -> Result<Option<RefValue>, String>

Performs a direct method call on a value.

This function is designed to invoke methods on values directly from Rust code.

pub fn unary_op(self, op: &str) -> Result<RefValue, String>

pub fn binary_op(self, operand: RefValue, op: &str) -> Result<RefValue, String>
