Struct tabin_plugins::procfs::MemInfo

pub struct MemInfo {
    pub total: Option<usize>,
    pub available: Option<usize>,
    pub free: Option<usize>,
    pub cached: Option<usize>,
}

A struct that represents overall memory usage on the system.

All values are in KB.

Fields

total: Option<usize>

available: Option<usize>

free: Option<usize>

cached: Option<usize>

Implementations

impl MemInfo

pub fn load() -> MemInfo

Read the data from /proc/meminfo into a MemInfo

pub fn percent_free(&self) -> Result<f64>

Try to figure out how much memory is being used

Since linux kernel 3.16 this just performs

    available / total * 100

Before that we approximate available as Free + Cached, even though that is almost certain to be incorrect.

pub fn percent_used(&self) -> Result<f64>

The inverse of MemInfo::percent_free

Trait Implementations

impl Debug for MemInfo

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

Formats the value using the given formatter.

impl Eq for MemInfo

impl FromStr for MemInfo

type Err = ProcFsError

The associated error which can be returned from parsing.

fn from_str(meminfo: &str) -> Result<Self>

Convert the contents of a string like /proc/meminfo into a MemInfo object

impl PartialEq<MemInfo> for MemInfo

fn eq(&self, other: &MemInfo) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &MemInfo) -> bool

This method tests for !=.
