Struct CpuInfo

    pub vendor: CpuVendor,
    pub vendor_id: [u8; 12],
    pub features: CpuFeatures,
    pub supported_xcr0: u64,
    pub xsave_size_current: usize,

}

Cached CPU identification and feature information.

Fields

vendor: CpuVendor

vendor_id: [u8; 12]

Raw CPUID(0) vendor string (EBX:EDX:ECX, 12 bytes, not NUL-terminated). Preserves vendors classified as CpuVendor::Unknown by Self::vendor_string.

features: CpuFeatures

supported_xcr0: u64

Bitmap of extended state components the CPU supports (CPUID.(0D,0):EDX:EAX). Capability bitmap, not a maximum value.

xsave_size_current: usize

XSAVE area size (bytes) for the components enabled in XCR0 at detect() time (CPUID.(0D,0):EBX). Depends on the OS-enabled state — use xsave_size_for_xcr0 for arbitrary masks.

xsave_size_max: usize

XSAVE area size (bytes) required if every supported component were enabled (CPUID.(0D,0):ECX). Upper bound for synthetic XCR0 masks.

family: u16

model: u8

stepping: u8

model_name: [u8; 48]

model_name_len: usize

Implementations

impl CpuInfo

pub fn model_name_str(&self) -> &str

Return the model name as a &str.

pub fn vendor_string(&self) -> &'static str

Return a vendor id string (e.g. “GenuineIntel”).

impl CpuInfo

pub fn avx_usable(&self) -> bool

Whether AVX may actually be executed: the hardware announces it AND the kernel enabled the required states (CR4.OSXSAVE via XSAVE + XCR0 bits 0|1|2). Never gate code paths on features.contains(AVX) alone : that only reflects CPUID, not what the OS programmed.

pub fn avx512_usable(&self) -> bool

Whether AVX-512 may actually be executed: hardware support plus all required XCR0 states enabled (opmask, ZMM_Hi256, HI16_ZMM on top of x87/SSE/AVX). See avx_usable.

Trait Implementations

impl Clone for CpuInfo

fn clone(&self) -> CpuInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CpuInfo

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

Formats the value using the given formatter.
