Struct Version

pub struct Version {
    pub major: u8,
    pub minor: u8,
    pub patch: u16,
}

Represents a kernel version, in major.minor.release version.

Fields

major: u8

minor: u8

patch: u16

Implementations

impl Version

pub fn new(major: u8, minor: u8, patch: u16) -> Version

pub fn current() -> ProcResult<Self>

Returns the kernel version of the currently running kernel.

This is taken from /proc/sys/kernel/osrelease;

pub fn from_str(s: &str) -> Result<Self, &'static str>

Parses a kernel version string, in major.minor.release syntax.

Note that any extra information (stuff after a dash) is ignored.

Example

let a = KernelVersion::from_str("3.16.0-6-amd64").unwrap();
let b = KernelVersion::new(3, 16, 0);
assert_eq!(a, b);

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Version

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

Formats the value using the given formatter.

impl FromStr for Version

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

Parses a kernel version string, in major.minor.release syntax.

Note that any extra information (stuff after a dash) is ignored.

Example

let a: KernelVersion = "3.16.0-6-amd64".parse().unwrap();
let b = KernelVersion::new(3, 16, 0);
assert_eq!(a, b);

type Err = &'static str

The associated error which can be returned from parsing.

impl Hash for Version

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.

impl Ord for Version

fn cmp(&self, other: &Self) -> 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 Version

fn eq(&self, other: &Version) -> 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 Version

fn partial_cmp(&self, other: &Self) -> 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.
