Struct tokay::value::RefValue

pub struct RefValue { /* private fields */ }

Implementations

impl RefValue

pub fn ref_or_copy(self) -> Self

Either creates a copy of a value or a reference, which is configured by the is_mutable() function of the underlying object.

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

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

pub fn call_method( &self, name: &str, context: Option<&mut Context<'_, '_, '_, '_>>, 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>
