Struct CpuInfo

pub struct CpuInfo { /* private fields */ }

Represent the content of the /proc/cpuinfo, returned by cpuinfo().

It is an Vec<Process> actually, but provides two useful method : logical_core_num() and physical_core_num()

This struct implement Index trait.

Implementations

impl CpuInfo

pub fn logical_core_num(&self) -> usize

Return logical core number

This is the numbers of the entry in /proc/cpuinfo.

pub fn physical_core_num(&self) -> usize

Return physical core number

This is caculated from core id.

Note: This method will panic if core id doesn’t appear.

Field core id only appears on SMP machine. In this case, physical core numbers equals to logical core numbers.

Trait Implementations

impl Clone for CpuInfo

fn clone(&self) -> CpuInfo

Returns a copy 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 FromStr for CpuInfo

type Err = ProcErr

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<CpuInfo, ProcErr>

Parses a string s to return a value of this type.

impl Index<usize> for CpuInfo

type Output = Processor

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl PartialEq for CpuInfo

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