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());
}
