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());

Structs

Struct containing a component information (temperature and name for the moment).

Struct containing a disk information.

Type containing read and written bytes.

A group id wrapping a platform specific type

A struct representing system load average value.

Contains network information.

Network interfaces.

Iterator over network interfaces.

Struct containing a process’ information.

Struct containing a processor information.

Used to determine what you want to refresh specifically on System type.

Structs containing system’s information.

A user id wrapping a platform specific type

Type containing user information.

Enums

Enum containing the different supported disks types.

Enum describing the different status of a process.

An enum representing signals on UNIX-like systems.

Traits

Trait to have a common fallback for the Pid type.

Getting a component temperature information.

Contains all the methods of the Disk struct.

Getting volume of received and transmitted data.

Interacting with network interfaces.

Contains all the methods of the Process struct.

Contains all the methods of the Processor struct.

Contains all the methods of the System type.

Getting information for a user.

Functions

Returns the pid for the current process.

This function is only used on linux targets, on the other platforms it does nothing and returns false.

Type Definitions

Process id.
