sysinfo系统信息获取库

sysinfo 是 Rust 编写的用于获取系统信息的库。

支持以下操作系统

• Android


• iOS


• Linux


• macOS


• Raspberry Pi


• Windows

示例

use sysinfo::{NetworkExt, NetworksExt, ProcessExt, System, SystemExt};



// Please note that we use "new_all" to ensure that all list of

// components, network interfaces, disks and users are already

// filled!

let mut sys = System::new_all();



// First we update all information of our `System` struct.

sys.refresh_all();



// We display all disks' information:

println!("=> disks:");

for disk in sys.disks() {

    println!("{:?}", disk);

}



// Network interfaces name, data received and data transmitted:

println!("=> networks:");

for (interface_name, data) in sys.networks() {

    println!("{}: {}/{} B", interface_name, data.received(), data.transmitted());

}



// Components temperature:

println!("=> components:");

for component in sys.components() {

    println!("{:?}", component);

}



println!("=> system:");

// RAM and swap information:

println!("total memory: {} KB", sys.total_memory());

println!("used memory : {} KB", sys.used_memory());

println!("total swap  : {} KB", sys.total_swap());

println!("used swap   : {} KB", sys.used_swap());



// Display system information:

println!("System name:             {:?}", sys.name());

println!("System kernel version:   {:?}", sys.kernel_version());

println!("System OS version:       {:?}", sys.os_version());

println!("System host name:        {:?}", sys.host_name());



// Number of processors:

println!("NB processors: {}", sys.processors().len());



// Display processes ID, name na disk usage:

for (pid, process) in sys.processes() {

    println!("[{}] {} {:?}", pid, process.name(), process.disk_usage());

}
