Struct heapless::pool::singleton::Box

pub struct Box<POOL, STATE = Init> where
    POOL: Pool,
    STATE: 'static,  { /* fields omitted */ }

A memory block that belongs to the global memory pool, POOL

Implementations

impl<P> Box<P, Uninit> where
    P: Pool, 

pub fn init(self, val: P::Data) -> Box<P, Init>

Initializes this memory block

impl<P> Box<P, Uninit> where
    P: Pool,
    P::Data: AsSlice<Element = u8>, 

pub fn freeze(self) -> Box<P, Init>

Freezes the contents of this memory block

See rust-lang/rust#58363 for details.

impl<P> Box<P, Init> where
    P: Pool, 

pub fn forget(self) -> Box<P, Uninit>

Forgets the contents of this memory block without running its destructor.

Note that this this does not return the memory block to the pool. The block can be reused, or returned to the pool by dropping it.
