Struct SysInfo

#[repr(C)]
pub struct SysInfo {
    pub version: u32,
    pub flags: u32,
    pub cpu_count: usize,
    pub page_size: usize,
}

Information about the system.

Fields

version: u32

The version of this data structure, to allow expansion.

flags: u32

Flags. Currently unused.

cpu_count: usize

The number of CPUs on this system. Hyperthreads are counted as individual CPUs.

page_size: usize

The size of a virtual address page on this system.

Implementations

impl SysInfo

pub fn cpu_count(&self) -> NonZeroUsize

Get the number of CPUs on the system.

pub fn page_size(&self) -> usize

Get the page size of the system.

Trait Implementations

impl Clone for SysInfo

fn clone(&self) -> SysInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SysInfo

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

Formats the value using the given formatter.

impl Ord for SysInfo

fn cmp(&self, other: &SysInfo) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SysInfo

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

impl PartialOrd for SysInfo

fn partial_cmp(&self, other: &SysInfo) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
