Struct Cpsr 

pub struct Cpsr {
    pub mode: Mode,
    pub fiq_disable: bool,
    pub irq_disable: bool,
    pub flags: Flags,
}

The full CPSR (or an SPSR): mode + interrupt-mask bits + the Flags condition codes.

Fields

mode: Mode

The active processor mode (see the mode module).

fiq_disable: bool

FIQ (fast-interrupt) mask — set to disable FIQ.

irq_disable: bool

IRQ mask — set to disable normal interrupts.

flags: Flags

The N/Z/C/V condition-code flags.

Implementations

impl Cpsr

pub const fn to_u32(self) -> u32

Pack into the 32-bit CPSR/SPSR register layout (Mesen2 ArmV3CpuFlags::ToInt32) — used by MRS and the (not-yet-ported) exception-entry path. self.mode is masked to its real 5-bit width here too (belt-and-suspenders on top of Regs::switch_mode’s own mask, so a stray high bit can never leak into the adjacent interrupt-mask/reserved bits regardless of how mode was set).

Trait Implementations

impl Clone for Cpsr

fn clone(&self) -> Cpsr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cpsr

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

Formats the value using the given formatter.

impl Default for Cpsr

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Cpsr

fn eq(&self, other: &Cpsr) -> 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.
