Crate sysinfo[−][src]

Expand description

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

Supported Oses

It currently supports the following OSes (alphabetically sorted):

Android
iOS
Linux
macOS
Windows

You can still use sysinfo on non-supported OSes, it’ll simply do nothing and always return empty values. You can check in your program directly if an OS is supported by checking the SystemExt::IS_SUPPORTED constant.

Usage

/!\ Before any attempt to read the different structs’ information, you need to update them to get up-to-date information because for most of them, it works on diff between the current value and the old one.

Which is why, it’s much better to keep the same instance of System around instead of recreating it multiple times.

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.processes() {
    println!("{}:{} => status: {:?}", pid, proc_.name(), proc_.status());
}

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

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

// And finally the RAM and SWAP information:
println!("total memory: {} KB", system.total_memory());
println!("used memory : {} KB", system.used_memory());
println!("total swap  : {} KB", system.total_swap());
println!("used swap   : {} KB", system.used_swap());

// Display system information:
println!("System name:             {:?}", system.name());
println!("System kernel version:   {:?}", system.kernel_version());
println!("System OS version:       {:?}", system.os_version());
println!("System host name:        {:?}", system.host_name());
