Struct pid_allocator::PidAllocator

pub struct PidAllocator<const ORDER: usize> { /* private fields */ }

A thread-safe PID allocator that can allocate and recycle PIDs efficiently. It encapsulates the allocator’s state within an Arc<SpinMutex<...>> to allow safe shared access across threads.

Implementations

impl<const ORDER: usize> PidAllocator<ORDER>

pub fn new() -> Self

Creates a new instance of the PID allocator.

pub fn allocate(&self) -> Option<Pid<ORDER>>

Attempts to allocate a new PID. Returns Some(Pid) if successful, or None if all PIDs are currently allocated. The allocated PID is wrapped in a Pid object, which will automatically recycle the PID when dropped.

Trait Implementations

impl<const ORDER: usize> Debug for PidAllocator<ORDER>

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

Formats the value using the given formatter.

impl<const ORDER: usize> Default for PidAllocator<ORDER>

fn default() -> PidAllocator<ORDER>

Returns the “default value” for a type.
