# Struct [tauri_api](/docs/api/rust/tauri_api/../index.html)::​[process](/docs/api/rust/tauri_api/index.html)::​[System](/docs/api/rust/tauri_api/)

    pub struct System { /* fields omitted */ }

Structs containing system's information.

## Trait Implementations

### `impl Debug for System`

#### `fn fmt(&self, f: &mut Formatter) -> Result<(), Error>`

Formats the value using the given formatter. [Read more](https://doc.rust-lang.org/nightly/core/fmt/trait.Debug.html#tymethod.fmt)

### `impl Default for System`

#### `fn default() -> System`

Returns the "default value" for a type. [Read more](https://doc.rust-lang.org/nightly/core/default/trait.Default.html#tymethod.default)

### `impl SystemExt for System`

#### `fn new_with_specifics(refreshes: RefreshKind) -> System`

Creates a new \[`System`] instance and refresh the data corresponding to the given \[`RefreshKind`]. [Read more](/docs/api/rust/tauri_api/../../tauri_api/process/trait.SystemExt.html#tymethod.new_with_specifics)

#### `fn refresh_memory(&mut self)`

Refresh RAM and SWAP usage.

#### `fn refresh_cpu(&mut self)`

Refresh CPU usage.

#### `fn refresh_temperatures(&mut self)`

Refresh components' temperature.

#### `fn refresh_processes(&mut self)`

Get all processes and update their information.

#### `fn refresh_process(&mut self, pid: i32) -> bool`

Refresh only the process corresponding to `pid`. Returns `false` if the process doesn't exist. [Read more](/docs/api/rust/tauri_api/../../tauri_api/process/trait.SystemExt.html#tymethod.refresh_process)

#### `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<i32, Process, RandomState>`

Returns the process list.

#### `fn get_process(&self, pid: i32) -> Option<&Process>`

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

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

Returns network data.

#### `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_uptime(&self) -> u64`

Returns system uptime.

#### `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). [Read more](/docs/api/rust/tauri_api/../../tauri_api/process/trait.SystemExt.html#method.new)

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

Refreshes according to the given \[`RefreshKind`]. It calls the corresponding "refresh\_" methods. [Read more](/docs/api/rust/tauri_api/../../tauri_api/process/trait.SystemExt.html#method.refresh_specifics)

#### `fn refresh_system(&mut self)`

Refresh system information (such as memory, swap, CPU usage and components' temperature). [Read more](/docs/api/rust/tauri_api/../../tauri_api/process/trait.SystemExt.html#method.refresh_system)

#### `fn refresh_all(&mut self)`

Refreshes all system, processes and disks information.

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

Returns a list of process containing the given `name`.
