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

# Struct std::collections::vec_deque::PlaceFront [−] [src]

    #[must_use = "places do nothing unless written to with `<-` syntax"]
    pub struct PlaceFront<'a, T> where
        T: 'a,  { /* fields omitted */ }

🔬 This is a nightly-only experimental API. (`collection_placement` #30172)

struct name and placement protocol are subject to change

A place for insertion at the front of a `VecDeque`.

See `VecDeque::place_front` for details.

## Trait Implementations

### `impl<'a, T> Placer<T> for PlaceFront<'a, T>`
[src]

#### `type Place = PlaceFront<'a, T>`

🔬 This is a nightly-only experimental API. (`placement_new_protocol` #27779)

`Place` is the intermedate agent guarding the uninitialized state for `Data`. Read more

#### `fn make_place(self) -> PlaceFront<'a, T>`

🔬 This is a nightly-only experimental API. (`placement_new_protocol` #27779)

Creates a fresh place from `self`.

### `impl<'a, T> Place<T> for PlaceFront<'a, T>`
[src]

#### `fn pointer(&mut self) -> *mut T`

🔬 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, T> InPlace<T> for PlaceFront<'a, T>`
[src]

#### `type Owner = &'a mut T`

🔬 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) -> &'a mut T`

🔬 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

### `impl<'a, T> Debug for PlaceFront<'a, T> where
T: 'a + Debug,`
[src]

#### `fn fmt(&self, __arg_0: &mut Formatter) -> Result<(), Error>`

Formats the value using the given formatter.

## 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`)
