    pub subleaf: u32,
    /* private fields */
}

Available on crate feature dep_raw_cpuid only.

ExtendedState subleaf structure for things that need to be restored.

Fields

subleaf: u32

Implementations

impl ExtendedState

pub fn register(&self) -> ExtendedRegisterType

Returns which register this specific extended subleaf contains information for.

pub fn size(&self) -> u32

The size in bytes (from the offset specified in EBX) of the save area for an extended state feature associated with a valid sub-leaf index, n. This field reports 0 if the sub-leaf index, n, is invalid.

pub fn offset(&self) -> u32

The offset in bytes of this extended state components save area from the beginning of the XSAVE/XRSTOR area.

pub fn location(&self) -> ExtendedRegisterStateLocation

pub fn is_in_ia32_xss(&self) -> bool

True if the bit n (corresponding to the sub-leaf index) is supported in the IA32_XSS MSR;

Deprecation note

This will likely be removed in the future. Use location() instead.

pub fn is_in_xcr0(&self) -> bool

True if bit n is supported in XCR0.

Deprecation note

This will likely be removed in the future. Use location() instead.

pub fn is_compacted_format(&self) -> bool

Returns true when the compacted format of an XSAVE area is used, this extended state component located on the next 64-byte boundary following the preceding state component (otherwise, it is located immediately following the preceding state component).

Trait Implementations

impl Debug for ExtendedState

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

Formats the value using the given formatter.
