Enum MachineAction 

pub enum MachineAction {
    Clear,
    Run(String),
}

Actions that callables can request the Machine to perform after an upcall returns.

Because callables don’t have direct access to the Machine, they push requests onto an action queue. The Machine’s exec loop drains this queue after each upcall, performing any requested side effects before resuming execution.

Variants

Clear

Reset all runtime state (variables, heap, clearables, last error).

Run(String)

Switches execution to the given program.

Trait Implementations

impl Clone for MachineAction

fn clone(&self) -> MachineAction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MachineAction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MachineAction

fn eq(&self, other: &MachineAction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
