Struct lc3_ensemble::sim::SimFlags

pub struct SimFlags {
    pub strict: bool,
    pub use_real_halt: bool,
    pub machine_init: MachineInitStrategy,
    pub debug_frames: bool,
}

Configuration flags for Simulator.

These can be modified after the Simulator is created with Simulator::new and their effects should still apply.

Read the field descriptions for more details.

Fields

strict: bool

Whether strict mode is enabled.

Strict mode adds additional integrity checks to the simulator, such as verifying initialization state is normal for provided data.

use_real_halt: bool

Whether to use the real HALT trap.

There are two implementations of HALT within Simulator:

• virtual HALT: On execution of HALT or TRAP x25, the simulator is automatically halted before executing any true TRAP routine.
• real HALT: On execution of HALT or TRAP x25, the TRAP routine for HALT implemented in the OS is run and executed as usual.

Real HALT is useful for maintaining integrity to the LC-3 ISA, whereas virtual HALT preserves the state of the machine prior to calling the OS’s HALT routine.

machine_init: MachineInitStrategy

The creation strategy for uninitialized Words.

This is used to initialize the mem and reg_file fields.

debug_frames: bool

Whether to store debugging information about call frames.

This flag only goes into effect after a Simulator::new or Simulator::reset call.

Trait Implementations

impl Clone for SimFlags

fn clone(&self) -> SimFlags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SimFlags

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

Formats the value using the given formatter.

impl Default for SimFlags

fn default() -> Self

The default flags.

They are defined as follows:

• strict: false
• use_real_halt: false
• machine_init: default MachineInitStrategy
• debug_frames: false

impl PartialEq for SimFlags

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

This method tests for self and other values to be equal, and is used by ==.

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

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