Struct CpuInfo

pub struct CpuInfo(/* private fields */);

Information about /proc/cpuinfo.

Implementations

impl CpuInfo

pub fn read() -> Result<Self, Error>

Read CPU information from /proc/cpuinfo.

Errors

Returns an std::io::Error if the file could not be read

pub fn read_from(filename: impl AsRef<Path>) -> Result<Self, Error>

Read CPU information from the given file.

Errors

Returns an std::io::Error if the file could not be read

pub fn cpu(&self, index: usize) -> Option<Cpu<'_>>

Return the CPU at the given index if it exists.

pub fn cpus(&self) -> impl Iterator<Item = Cpu<'_>>

Return an iterator over all available CPUs.

pub fn iter(&self) -> impl Iterator<Item = Cpu<'_>>

Return an iterator over all available CPUs.

This is the same as calling Self::cpus().

Trait Implementations

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

Read the CPU info from /proc/cpuinfo.

Panics

This method panics, if the file could not be read.

impl From<&str> for CpuInfo

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for CpuInfo

fn from(text: String) -> Self

Converts to this type from the input type.

impl FromStr for CpuInfo

type Err = Infallible

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

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.
