Trait Implementations

impl<'a, K: 'a + Debug, V: 'a + Debug> Debug for EntryPlace<'a, K, V>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'a, K, V> Drop for EntryPlace<'a, K, V>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a, K, V> Place<V> for EntryPlace<'a, K, V>

fn pointer(&mut self) -> *mut V

🔬 This is a nightly-only experimental API. (placement_new_protocol)

Returns the address where the input value will be written. Note that the data at this address is generally uninitialized, and thus one should use ptr::write for initializing it.

impl<'a, K, V> InPlace<V> for EntryPlace<'a, K, V>

type Owner = ()

🔬 This is a nightly-only experimental API. (placement_new_protocol)

Owner is the type of the end value of PLACE <- EXPR

unsafe fn finalize(self)

🔬 This is a nightly-only experimental API. (placement_new_protocol)

Converts self into the final value, shifting deallocation/cleanup responsibilities (if any remain), over to the returned instance of Owner and forgetting self.
