Struct muse_lang::vm::VmState

pub struct VmState { /* private fields */ }

The state of a Vm.

Virtual machines are garbage collected types, which requires interior mutability so that the garbage collector can trace what every allocated virtual machine is currently referencing.

Implementations

impl VmState

pub fn set_steps_per_charge(&mut self, steps: u16)

Sets the number of virtual machine steps to take per budget being charged.

This also affects how often the virtual machine checks if it should yield to the garbage collector.

pub const fn registers(&self) -> &[Value; 256]

Returns a slice of the registers.

pub fn registers_mut(&mut self) -> &mut [Value; 256]

Returns exclusive access to the registers.

pub fn current_module(&self) -> ModuleId

Returns the id of the module that owns the code currently executing.

pub fn root_module(&self) -> Dynamic<Module>

Returns the root module for this virtual machine.
