Struct BuildInfo

pub struct BuildInfo {
    pub version: String,
    pub flags: HashSet<String>,
    pub extra: String,
}

Represents a kernel build information

Fields

version: String

flags: HashSet<String>

extra: String

This field contains any extra data from the /proc/sys/kernel/version file. It generally contains the build date of the kernel, but the format of the date can vary.

A method named extra_date is provided which would try to parse some date formats. When the date format is not supported, an error will be returned. It depends on chrono feature.

Implementations

impl BuildInfo

pub fn new(version: &str, flags: HashSet<String>, extra: String) -> BuildInfo

pub fn smp(&self) -> bool

Check if SMP is ON

pub fn preempt(&self) -> bool

Check if PREEMPT is ON

pub fn preemptrt(&self) -> bool

Check if PREEMPTRT is ON

pub fn version_number(&self) -> ProcResult<u32>

Return version number

This would parse number from first digits of version string. For example, #21~1 to 21.

pub fn extra_date(&self) -> ProcResult<DateTime<Local>>

Parse extra field to DateTime object

This function may fail as TIMESTAMP can be various formats.

Trait Implementations

impl Clone for BuildInfo

fn clone(&self) -> BuildInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BuildInfo

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

Formats the value using the given formatter.

impl FromStr for BuildInfo

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

Parse a kernel build information string

type Err = &'static str

The associated error which can be returned from parsing.

impl PartialEq for BuildInfo

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