Implementations§

Source§

impl SysInfo

Source

pub fn load_average(&self) -> (f64, f64, f64)

Returns the load average tuple.

The returned values represent the load average over time intervals of 1, 5, and 15 minutes, respectively.

Source

pub fn uptime(&self) -> Duration

Returns the time since system boot.

Source

pub fn process_count(&self) -> u16

Current number of processes.

Source

pub fn swap_total(&self) -> u64

Returns the amount of swap memory in Bytes.

Source

pub fn swap_free(&self) -> u64

Returns the amount of unused swap memory in Bytes.

Source

pub fn ram_total(&self) -> u64

Returns the total amount of installed RAM in Bytes.

Source

pub fn ram_unused(&self) -> u64

Returns the amount of completely unused RAM in Bytes.

“Unused” in this context means that the RAM in neither actively used by programs, nor by the operating system as disk cache or buffer. It is “wasted” RAM since it currently serves no purpose.
