[−][src]Struct freezebox::FreezeBox

pub struct FreezeBox<T> { /* fields omitted */ }

FreezeBox is a deref'able lazy-initialized container.

A FreezeBox<T> can have two possible states:

  • uninitialized: deref is not allowed.
  • initialized: deref to a &T is possible.

To upgrade a FreezeBox to the initialized state, call lazy_init. lazy_init does not require a mutable reference, making FreezeBox suitable for sharing objects first and initializing them later.

Attempting to lazy_init more than once, or deref while uninitialized will cause a panic.

Implementations

impl<T> FreezeBox<T>[src]

pub fn new() -> Self[src]

Create an uninitialized FreezeBox.

pub fn lazy_init(&self, val: T)[src]

Initialize a FreezeBox.

lazy_init will panic if the FreezeBox is already initialized.
