# Trait ethcore_util::standard::ops::InPlace [−] [src]

    pub trait InPlace<Data>: Place<Data> where Data: ?Sized {
        type Owner;
        unsafe fn finalize(self) -> Self::Owner;
    }

Unstable (`placement_new_protocol`)

Specialization of `Place` trait supporting `in (PLACE) EXPR`.

## Associated Types

### `type Owner`

Unstable (`placement_new_protocol`)

`Owner` is the type of the end value of `in (PLACE) EXPR`

Note that when `in (PLACE) EXPR` is solely used for side-effecting an existing data-structure, e.g. `Vec::emplace_back`, then `Owner` need not carry any information at all (e.g. it can be the unit type `()` in that case).

## Required Methods

### `unsafe fn finalize(self) -> Self::Owner`

Unstable (`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.

## 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`)
