Struct PrivateCell

Source 
pub struct PrivateCell<T>(T);
Expand description

Encapsulates a field of Thread that can only be accessed by the CPU that currently executing the thread.

§Context safety

Default implementation of this type does not require a CPU context as long as implementation on T does not.

impl<T> PrivateCell<T>

Source

fn validate(&self, owner: &Thread)

Source§

impl<T> PrivateCell<Cell<T>>

Source

pub unsafe fn set(&self, owner: &Thread, v: T)
