Struct dirty_static::DirtyStatic

pub struct DirtyStatic<T>(_);

A container for a value which allows interior mutation only in debug mode. (Or when enabled via force-dynamic feature.)

Methods

impl<T> DirtyStatic<T>

pub const fn new(t: T) -> Self

Create a new DirtyStatic with the given interior value.

Examples

use dirty_static::DirtyStatic;

let c = DirtyStatic::new(100);
assert_eq!(*c, 100);

pub unsafe fn replace(&self, t: T)

Replace the interior value of the DirtyStatic. Note that this will do nothing unless running in debug mode, or enabling the force-dynamic feature.

Examples

// In debug mode
use dirty_static::DirtyStatic;

let c = DirtyStatic::new(100);
unsafe {
    c.replace(200);
}

assert_eq!(*c, 200);

// In release mode
use dirty_static::DirtyStatic;

let c = DirtyStatic::new(100);
unsafe {
    c.replace(200);
}

assert_eq!(*c, 100);
