Struct State

pub struct State<'a, Buffer: IoWrite> { /* private fields */ }

State of the virtual machine

Implementations

impl<'a, Buffer: IoWrite> State<'a, Buffer>

pub fn get_string_by_id(&self, id: usize) -> Option<&str>

Get string by string id

Return None if id is invalid. If id is provided by parameters, it can never be invalid and thus is safe to unwrap.

pub fn create_str(&mut self, s: String) -> usize

Create a new string

Return reference id to the string which can be put into DiatomValue::Str().

pub fn create_user_data(&mut self, data: Box<dyn Any + Send>) -> usize

pub fn get_obj_mut( &mut self, ref_id: usize, ) -> Option<DiatomObjectMut<'_, Buffer>>

Get a mutable reference by reference id

Return None if id is invalid. If id is provided by parameters, it can never be invalid and thus is safe to unwrap.

pub fn get_obj(&self, ref_id: usize) -> Option<DiatomObject<'_, Buffer>>

Same as get_obj_mut but this is immutable

This is much cheaper than a mutable borrow.

pub fn print(&self, value: &DiatomValue) -> String

pub fn collect_garbage(&mut self)

Immediately collect garbage

pub fn pause_gc(&mut self)

Pause garbage collection

Do nothing if gc is already paused.

pub fn resume_gc(&mut self)

Resume garbage collection

Do nothing if gc is not paused.
