}
|
||
|
||
Contains all the methods of the `Process` struct.
|
||
|
||
## Required methods
|
||
|
||
### `fn new(pid: i32, parent: Option<i32>, start_time: u64) -> Self`
|
||
|
||
Create a new process only containing the given information.
|
||
|
||
On windows, the `start_time` argument is ignored.
|
||
|
||
### `fn kill(&self, signal: Signal) -> bool`
|
||
|
||
Sends the given `signal` to the process.
|
||
|
||
### `fn name(&self) -> &str`
|
||
|
||
Returns the name of the process.
|
||
|
||
### `fn cmd(&self) -> &[String]`
|
||
|
||
Returns the command line.
|
||
|
||
### `fn exe(&self) -> &Path`
|
||
|
||
Returns the path to the process.
|
||
|
||
### `fn pid(&self) -> i32`
|
||
|
||
Returns the pid of the process.
|
||
|
||
### `fn environ(&self) -> &[String]`
|
||
|
||
Returns the environment of the process.
|
||
|
||
Always empty on Windows except for current process.
|
||
|
||
### `fn cwd(&self) -> &Path`
|
||
|
||
Returns the current working directory.
|
||
|
||
Always empty on Windows.
|
||
|
||
### `fn root(&self) -> &Path`
|
||
|
||
Returns the path of the root directory.
|
||
|
||
Always empty on Windows.
|
||
|
||
### `fn memory(&self) -> u64`
|
||
|
||
Returns the memory usage (in KiB).
|
||
|
||
### `fn virtual_memory(&self) -> u64`
|
||
|
||
Returns the virtual memory usage (in KiB).
|
||
|
||
### `fn parent(&self) -> Option<i32>`
|
||
|
||
Returns the parent pid.
|
||
|
||
### `fn status(&self) -> ProcessStatus`
|
||
|
||
Returns the status of the processus.
|
||
|
||
### `fn start_time(&self) -> u64`
|
||
|
||
Returns the time of process launch (in seconds).
|
||
|
||
### `fn cpu_usage(&self) -> f32`
|
||
|
||
Returns the total CPU usage.

## Implementors
|
||
|
||
### `impl ProcessExt for Process`
|
||
|
||
#### `fn new(pid: i32, parent: Option<i32>, start_time: u64) -> Process`
|
||
|
||
#### `fn kill(&self, signal: Signal) -> bool`
|
||
|
||
#### `fn name(&self) -> &str`
|
||
|
||
#### `fn cmd(&self) -> &[String]`
|
||
|
||
#### `fn exe(&self) -> &Path`
|
||
|
||
#### `fn pid(&self) -> i32`
|
||
|
||
#### `fn environ(&self) -> &[String]`
|
||
|
||
#### `fn cwd(&self) -> &Path`
|
||
|
||
#### `fn root(&self) -> &Path`
|
||
|
||
#### `fn memory(&self) -> u64`
|
||
|
||
#### `fn virtual_memory(&self) -> u64`
|
||
|
||
#### `fn parent(&self) -> Option<i32>`
|
||
|
||
#### `fn status(&self) -> ProcessStatus`
|
||
|
||
Returns the status of the processus (idle, run, zombie, etc). `None` means that `sysinfo` doesn't have enough rights to get this information.
|
||
|
||
#### `fn start_time(&self) -> u64`
|
||
|
||
#### `fn cpu_usage(&self) -> f32`
