Immortal

Struct Immortal 

Source
pub struct Immortal<T> { /* private fields */ }
Expand description

A value that is truly owned by the process itself.

Using this type is similar to using a ProcessOwned with lazy_static, except the value can only be dropped when the process terminates. This can lead to memory leaks, but it can also be useful for values that are used throughout the entire process.

Implementations§

Source§

impl<T> Immortal<T>

Source

pub unsafe fn new(value: T) -> Self

Creates a new Immortal value.

§Safety

This function is unsafe because it allocates memory and stores a raw pointer to it. The memory is never freed, so it is up to the caller to ensure that the memory is not leaked.

§Examples
use process_owned::Immortal;
 
unsafe {
    let immortal = Immortal::new(5);
    assert_eq!(*immortal, 5);
}
