Struct RegistersMut 

pub struct RegistersMut<'a> { /* private fields */ }

RAII guard returned by Cpu::registers_mut.

Dereferences to Registers, giving full read/write access to all programmer-visible registers. On drop the guard arms the NMI if the hardware stack pointer (S) changed during the guard’s lifetime.

Methods from Deref<Target = Registers>

pub fn set_a(&mut self, val: u8)

Write accumulator A (high byte of D), preserving B.

pub fn set_b(&mut self, val: u8)

Write accumulator B (low byte of D), preserving A.

Trait Implementations

impl Deref for RegistersMut<'_>

type Target = Registers

The resulting type after dereferencing.

fn deref(&self) -> &Registers

Dereferences the value.

impl DerefMut for RegistersMut<'_>

fn deref_mut(&mut self) -> &mut Registers

Mutably dereferences the value.

impl Drop for RegistersMut<'_>

fn drop(&mut self)

Executes the destructor for this type.
