Struct Permanent 

pub struct Permanent<T: 'static> { /* private fields */ }

Handle that mimics a 'static reference.

Thread Safety: Can be used anywhere and does not produce any form of overhead.

Implementations

impl<T: 'static> Permanent<T>

pub fn new(value: Box<T>) -> Self

Create a new instance.

pub unsafe fn drop_permanent(self)

Drop the stored value.

Safety

The caller MUST ensure that:

• No other copies of this Permanent<T> (or any references derived from it) exist anywhere in the program.
• This function is called exactly once for the allocated memory.
