Struct Box

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

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

Implementations§

source§

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

source

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

Initializes this memory block

source§

impl<P> Box<P, Uninit>
where P: Pool, P::Data: AsRef<[u8]>,

source

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

👎Deprecated since 0.7.3: This can access uninitialized memory, use init(..) instead (https://github.com/japaric/heapless/issues/212)

(DO NOT USE, SEE DEPRECATION) Freezes the contents of this memory block

See rust-lang/rust#58363 for details.

source§

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

source

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.
