[]Struct x86_64::registers::rflags::RFlags

pub struct RFlags { /* fields omitted */ }

The RFLAGS register.

Methods

impl RFlags

pub const ID: RFlags

Processor feature identification flag.

If this flag is modifiable, the CPU supports CPUID.

pub const VIRTUAL_INTERRUPT_PENDING: RFlags

Indicates that an external, maskable interrupt is pending.

Used when virtual-8086 mode extensions (CR4.VME) or protected-mode virtual interrupts (CR4.PVI) are activated.

pub const VIRTUAL_INTERRUPT: RFlags

Virtual image of the INTERRUPT_FLAG bit.

Used when virtual-8086 mode extensions (CR4.VME) or protected-mode virtual interrupts (CR4.PVI) are activated.

pub const ALIGNMENT_CHECK: RFlags

Enable automatic alignment checking if CR0.AM is set. Only works if CPL is 3.

pub const VIRTUAL_8086_MODE: RFlags

Enable the virtual-8086 mode.

pub const RESUME_FLAG: RFlags

Allows to restart an instruction following an instrucion breakpoint.

pub const NESTED_TASK: RFlags

Used by iret in hardware task switch mode to determine if current task is nested.

pub const IOPL_HIGH: RFlags

The high bit of the I/O Privilege Level field.

Specifies the privilege level required for executing I/O address-space instructions.

pub const IOPL_LOW: RFlags

The low bit of the I/O Privilege Level field.

Specifies the privilege level required for executing I/O address-space instructions.

pub const OVERFLOW_FLAG: RFlags

Set by hardware to indicate that the sign bit of the result of the last signed integer operation differs from the source operands.

pub const DIRECTION_FLAG: RFlags

Determines the order in which strings are processed.

pub const INTERRUPT_FLAG: RFlags

Enable interrupts.

pub const TRAP_FLAG: RFlags

Enable single-step mode for debugging.

pub const SIGN_FLAG: RFlags

Set by hardware if last arithmetic operation resulted in a negative value.

pub const ZERO_FLAG: RFlags

Set by hardware if last arithmetic operation resulted in a zero value.

pub const AUXILIARY_CARRY_FLAG: RFlags

Set by hardware if last arithmetic operation generated a carry ouf of bit 3 of the result.

pub const PARITY_FLAG: RFlags

Set by hardware if last result has an even number of 1 bits (only for some operations).

pub const CARRY_FLAG: RFlags

Set by hardware if last arithmetic operation generated a carry out of the most-significant bit of the result.

pub const fn empty() -> RFlags

Returns an empty set of flags

pub const fn all() -> RFlags

Returns the set containing all flags.

pub const fn bits(&self) -> u64

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u64) -> Option<RFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u64) -> RFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: RFlags) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: RFlags) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: RFlags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: RFlags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: RFlags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: RFlags, value: bool)

Inserts or removes the specified flags depending on the passed value.
