Struct CpuInfo 

pub struct CpuInfo {
    pub brand: String,
    pub logical_cores: usize,
    pub physical_cores: usize,
    pub arch: String,
    pub features: CpuFeatures,
    pub performance_cores: Option<usize>,

}

CPU topology and feature-set information.

Fields

brand: String

Human-readable brand string (e.g. “Intel(R) Core(TM) i9-14900K”).

logical_cores: usize

Number of logical cores (hyperthreads).

physical_cores: usize

Number of physical cores (approximate).

arch: String

Architecture family (x86_64, aarch64, …).

features: CpuFeatures

Set of detected CPU features.

performance_cores: Option<usize>

Performance-core count on a hybrid CPU (e.g. Intel 12th gen+ P-cores). None when undetectable (non-Windows currently — see detect_hybrid_core_counts) or when the CPU has no real P/E split (every core reporting the same EfficiencyClass, which is the common case, including this repo’s AMD Zen reference hardware).

efficiency_cores: Option<usize>

Efficiency-core count on a hybrid CPU. Same availability rules as performance_cores.

Trait Implementations

impl Clone for CpuInfo

fn clone(&self) -> Self

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.

impl Default for CpuInfo

fn default() -> Self

Returns the “default value” for a type.

impl Hash for CpuInfo

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.
