Struct TrackedThread

pub struct TrackedThread {
    pid: KernelPID,
    tcb: Option<*mut thread_t>,
}

A thread identified not only by its PID (which can be reused whenever the thread has quit) but also by a pointer to its thread control block. This gives a TrackedThread a better get_status() method that reliably reports Stopped even when the PID is reused.

A later implementation may stop actually having the pid in the struct and purely rely on the tcb (although that’ll need to become a lifetime’d reference to a cell by then).

Fields

pid: KernelPID

tcb: Option<*mut thread_t>

Implementations

impl TrackedThread

pub fn pid(&self) -> KernelPID

pub fn status(&self) -> Status

Like status of a KernelPID, but infallible: this returns Stopped if the PID has been re-used after our thread has stopped.

Trait Implementations

impl Debug for TrackedThread

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

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
