Trait Implementations

impl Debug for System

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for System

fn default() -> System

Returns the “default value” for a type.

impl SystemExt for System

const IS_SUPPORTED: bool

Returns true if this OS is supported. Please refer to the crate-level documentation to get the list of supported OSes.

fn new_with_specifics(refreshes: RefreshKind) -> System

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

fn refresh_components_list(&mut self)

Refreshes components list.

fn refresh_memory(&mut self)

Refreshes RAM and SWAP usage.

fn refresh_cpu(&mut self)

Refreshes CPU usage.

fn refresh_processes(&mut self)

Gets all processes and updates their information.

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

fn refresh_disks_list(&mut self)

The disk list will be emptied then completely recomputed.

fn refresh_users_list(&mut self)

Refreshes users list.

fn get_processes(&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_networks(&self) -> &Networks

Returns the network interfaces object.

fn get_networks_mut(&mut self) -> &mut Networks

Returns a mutable access to network interfaces.

fn get_global_processor_info(&self) -> &Processor

Returns “global” processors information (aka the addition of all the processors).

fn get_processors(&self) -> &[Processor]

Returns the list of the processors.

fn get_physical_core_count(&self) -> Option<usize>

Returns the number of physical cores on the processor or None if it couldn’t get it.

fn get_total_memory(&self) -> u64

Returns the RAM size in kB.

fn get_free_memory(&self) -> u64

Returns the amount of free RAM in kB.

fn get_available_memory(&self) -> u64

Returns the amount of available RAM in kB.

fn get_used_memory(&self) -> u64

Returns the amound of used RAM in kB.

fn get_total_swap(&self) -> u64

Returns the SWAP size in kB.

fn get_free_swap(&self) -> u64

Returns the amount of free SWAP in kB.

fn get_used_swap(&self) -> u64

Returns the amount of used SWAP in kB.

fn get_components(&self) -> &[Component]

Returns the components list.

fn get_components_mut(&mut self) -> &mut [Component]

Returns a mutable components list.

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

Returns the disks list.

fn get_disks_mut(&mut self) -> &mut [Disk]

Returns the disks list.

fn get_uptime(&self) -> u64

Returns system uptime (in seconds).

fn get_boot_time(&self) -> u64

Returns the time (in seconds) when the system booted since UNIX epoch.

fn get_load_average(&self) -> LoadAvg

Returns the system load average value.

fn get_users(&self) -> &[User]

Returns the users list.

fn get_name(&self) -> Option<String>

Returns the system name.

fn get_long_os_version(&self) -> Option<String>

Returns the system long os version (e.g “MacOS 11.2 BigSur”).

fn get_host_name(&self) -> Option<String>

Returns the system hostname based off DNS

fn get_kernel_version(&self) -> Option<String>

Returns the system’s kernel version.

fn get_os_version(&self) -> Option<String>

Returns the system version (e.g. for MacOS this will return 11.1 rather than the kernel version).

fn new() -> Self

Creates a new System instance with nothing loaded except the processors list. If you want to load components, network interfaces or the disks, you’ll have to use the refresh_*_list methods. SystemExt::refresh_networks_list for example.

fn new_all() -> Self

Creates a new System instance with everything loaded.

fn refresh_specifics(&mut self, refreshes: RefreshKind)

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

fn refresh_system(&mut self)

Refreshes system information (RAM, swap, CPU usage and components’ temperature).

fn refresh_components(&mut self)

Refreshes components’ temperature.

fn refresh_disks(&mut self)

Refreshes the listed disks’ information.

fn refresh_networks(&mut self)

Refreshes networks data.

fn refresh_networks_list(&mut self)

The network list will be updated: removing not existing anymore interfaces and adding new ones.

fn refresh_all(&mut self)

Refreshes all system, processes, disks and network interfaces information.

fn get_process_by_name(&self, name: &str) -> Vec<&Process>

Returns a list of process containing the given name.
