Struct ProcessId 

pub struct ProcessId(/* private fields */);

Process ID newtype for type safety

Wraps a u32 process ID to provide type safety and prevent accidental misuse. This ensures PIDs are only used in appropriate contexts and makes the code more self-documenting.

Examples

use torrust_tracker_deployer_lib::infrastructure::persistence::filesystem::process_id::ProcessId;

// Get current process ID
let pid = ProcessId::current();

// Create from raw value
let pid = ProcessId::from_raw(12345);

// Get raw value
let raw: u32 = pid.as_u32();

// Parse from string
let pid: ProcessId = "12345".parse().unwrap();

Implementations

impl ProcessId

pub fn current() -> Self

Get the current process ID

Examples

use torrust_tracker_deployer_lib::infrastructure::persistence::filesystem::process_id::ProcessId;

let current = ProcessId::current();
assert!(current.is_alive());

pub fn from_raw(pid: u32) -> Self

Create a ProcessId from a raw u32

Examples

use torrust_tracker_deployer_lib::infrastructure::persistence::filesystem::process_id::ProcessId;

let pid = ProcessId::from_raw(12345);
assert_eq!(pid.as_u32(), 12345);

pub fn as_u32(&self) -> u32

Get the raw u32 value

Examples

use torrust_tracker_deployer_lib::infrastructure::persistence::filesystem::process_id::ProcessId;

let pid = ProcessId::from_raw(12345);
assert_eq!(pid.as_u32(), 12345);

pub fn is_alive(&self) -> bool

Check if this process is currently alive

Uses platform-specific methods to check if the process exists.

Examples

use torrust_tracker_deployer_lib::infrastructure::persistence::filesystem::process_id::ProcessId;

let current = ProcessId::current();
assert!(current.is_alive());

let fake_pid = ProcessId::from_raw(999_999);
assert!(!fake_pid.is_alive());
