Struct std::collections::hash_map::EntryPlace

#[must_use = "places do nothing unless written to with `pub struct EntryPlace<'a, K: 'a, V: 'a> { /* fields omitted */ }🔬 This is a nightly-only experimental API.  (collection_placement #30172)struct name and placement protocol is subject to change
A place for insertion to a Entry.

See HashMap::entry for details.

            
              Trait Implementations
            
        impl<'a, K: 'a + Debug, V: 'a + Debug> Debug for EntryPlace<'a, K, V>[src]
fn fmt(&self, f: &mut Formatter) -> Result[src]
Formats the value using the given formatter. Read more
impl<'a, K, V> Drop for EntryPlace<'a, K, V>[src]
fn drop(&mut self)[src]
Executes the destructor for this type. Read more
impl<'a, K, V> Place<V> for EntryPlace<'a, K, V>[src]
fn pointer(&mut self) -> *mut V[src]
🔬 This is a nightly-only experimental API.  (placement_new_protocol #27779)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. Read more
impl<'a, K, V> InPlace<V> for EntryPlace<'a, K, V>[src]
type Owner = ()
🔬 This is a nightly-only experimental API.  (placement_new_protocol #27779)Owner is the type of the end value of PLACE <- EXPR Read more
unsafe fn finalize(self)[src]
🔬 This is a nightly-only experimental API.  (placement_new_protocol #27779)Converts self into the final value, shifting deallocation/cleanup responsibilities (if any remain), over to the returned instance of Owner and forgetting self. Read more

                Search Tricks

                
                    Prefix searches with a type followed by a colon (e.g.
                    fn:) to restrict the search to a given type.
                

                
                    Accepted types are: fn, mod,
                    struct, enum,
                    trait, type, macro,
                    and const.
                

                
                    Search functions by type signature (e.g.
                    vec -> usize or * -> vec)
