Implementations

impl Lvm

pub fn new() -> Self

Constructs a new Lvm.

pub fn run(&mut self, code: Code) -> Result<Value>

Execute a Code.

pub fn call(&mut self, callee: Value, args: Vec<Value>) -> Result<Value>

Call a callable Value with arguments.

pub fn set_global_variable(&mut self, key: String, value: Value)

Set the value of global variable.

pub fn get_global_variable(&self, key: &str) -> Option<Value>

Get the value of global variable.

pub fn get_builtin_variable(&self, name: &str) -> Option<Value>

Get the value of builtin variable.

pub fn get_builtin_str(&mut self, key: &str) -> Value

Get a builtin str.

pub fn iter_table(&mut self, table_value: Value) -> Value

Return an iterator Value from a Table Value.

pub fn new_gc_object<T: Trace + 'static>(&mut self, value: T) -> Gc<T>

Constructs a new Gc<T>.

pub fn new_str_value(&mut self, value: String) -> Value

pub fn new_table_value(&mut self, value: Table) -> Value

pub fn new_userdata_value(&mut self, value: UserData) -> Value

pub fn new_closure_value(&mut self, value: Closure) -> Value

pub fn new_ext_closure_value(&mut self, value: ExtClosure) -> Value

pub fn traceback(&self) -> Vec<TracebackFrame>

Get the traceback info of current stack frame.

pub unsafe fn gc(&mut self)

Run the garbage collection.

Safety

When calling this method, you have to ensure that all of Gc<T> can be traced by the root on stack frame.

Trait Implementations

impl Default for Lvm

fn default() -> Self

Returns the “default value” for a type.
