Contains all the methods of the [System] type.

Required methods

`fn new_with_specifics(refreshes: RefreshKind) -> Self`

Creates a new [System] instance and refresh the data corresponding to the given RefreshKind.

Example

use sysinfo::{RefreshKind, System, SystemExt};

// We want everything except disks.
let mut system = System::new_with_specifics(RefreshKind::everything().without_disk_list());

assert_eq!(system.get_disks().len(), 0);
assert!(system.get_process_list().len() > 0);

// If you want the disks list afterwards, just call the corresponding
// "refresh_disk_list":
system.refresh_disk_list();
assert!(system.get_disks().len() > 0);

`fn refresh_system(&mut self)`

Refresh system information (such as memory, swap, CPU usage and components' temperature).

`fn refresh_processes(&mut self)`

Get all processes and update their information.

`fn refresh_process(&mut self, pid: Pid) -> bool`

Refresh only the process corresponding to pid. Returns false if the process doesn't exist.

`fn refresh_disks(&mut self)`

Refreshes the listed disks' information.

`fn refresh_disk_list(&mut self)`

The disk list will be emptied then completely recomputed.

`fn refresh_network(&mut self)`

Refresh data network.

`fn get_process_list(&self) -> &HashMap<Pid, Process>`

Returns the process list.

`fn get_process(&self, pid: Pid) -> Option<&Process>`

Returns the process corresponding to the given pid or None if no such process exists.

`fn get_processor_list(&self) -> &[Processor]`

The first processor in the array is the "main" one (aka the addition of all the others).

`fn get_total_memory(&self) -> u64`

Returns total RAM size in KiB.

`fn get_free_memory(&self) -> u64`

Returns free RAM size in KiB.

`fn get_used_memory(&self) -> u64`

Returns used RAM size in KiB.

`fn get_total_swap(&self) -> u64`

Returns SWAP size in KiB.

`fn get_free_swap(&self) -> u64`

Returns free SWAP size in KiB.

`fn get_used_swap(&self) -> u64`

Returns used SWAP size in KiB.

`fn get_components_list(&self) -> &[Component]`

Returns components list.

`fn get_disks(&self) -> &[Disk]`

Returns disks' list.

`fn get_network(&self) -> &NetworkData`

Returns network data.

`fn get_uptime(&self) -> u64`

Returns system uptime.

Provided methods

`fn new() -> Self`

Creates a new [System] instance. It only contains the disks' list and the processes list at this stage. Use the refresh_all method to update its internal information (or any of the refresh_ method).

`fn refresh_specifics(&mut self, refreshes: RefreshKind)`

Refreshes according to the given RefreshKind. It calls the corresponding "refresh_" methods.

Examples

use sysinfo::{RefreshKind, System, SystemExt};

let mut s = System::new();

// Let's just update network data and processes:
s.refresh_specifics(RefreshKind::new().with_network().with_processes());
