Enum ProcessState 

Source 
#[non_exhaustive]
pub enum ProcessState {
    Starting,
    Running,
    Suspended,
    Stopping,
    Exited(i32),
}
Expand description

State of a kernel-managed process.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Starting

Process is initializing.

§

Running

Process is actively running.

§

Suspended

Process has been suspended (paused).

§

Stopping

Process is in the process of stopping.

§

Exited(i32)

Process has exited with a status code.

Implementations§

Source§

impl ProcessState

Source

pub fn can_transition_to(&self, next: &ProcessState) -> bool

Check whether a state transition is valid.

Valid transitions:

  • Starting -> Running | Exited
  • Running -> Suspended | Stopping | Exited
  • Suspended -> Running | Stopping | Exited
  • Stopping -> Exited
  • Exited -> (none)
