std::collections::hash_map::EntryPlace - Rust
Description: API documentation for the Rust `EntryPlace` struct in crate `std`.
Keywords: rust, rustlang, rust-lang, EntryPlace

# Struct std::collections::hash_map::EntryPlace [−] [src]

    #[must_use = "places do nothing unless written to with `<-` syntax"]
    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.

### `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`)
