Crate sysinfo

sysinfo is a crate used to get a system's information.

Before any attempt to read the different structs' information, you need to update them to get up-to-date information.

Examples

use sysinfo::{ProcessExt, SystemExt};

let mut system = sysinfo::System::new_all();

// First we update all information of our system struct.
system.refresh_all();

// Now let's print every process' id and name:
for (pid, proc_) in system.get_processes() {
    println!("{}:{} => status: {:?}", pid, proc_.name(), proc_.status());
}

// Then let's print the temperature of the different components:
for component in system.get_components() {
    println!("{:?}", component);
}

// And then all disks' information:
for disk in system.get_disks() {
    println!("{:?}", disk);
}

// And finally the RAM and SWAP information:
println!("total memory: {} KB", system.get_total_memory());
println!("used memory : {} KB", system.get_used_memory());
println!("total swap  : {} KB", system.get_total_swap());
println!("used swap   : {} KB", system.get_used_swap());

Enums

DiskType	Enum containing the different supported disks types.
ProcessStatus	Enum describing the different status of a process.

Traits

AsU32	Trait to have a common fallback for the Pid type.
ComponentExt	Getting a component temperature information.
DiskExt	Contains all the methods of the Disk struct.
NetworkExt	Getting volume of received and transmitted data.
NetworksExt	Interacting with network interfaces.

Functions

get_current_pid	Returns the pid for the current process.
set_open_files_limit	This function is only used on linux targets, on the other platforms it does nothing and returns false.
