Placement new in Rust
A simple wrapper around MaybeUninit
that allows one to simply and safely
initialize a struct field-by-field
```rust use place::place; use std::mem::MaybeUninit;
struct MyCoolStruct { b: bool, u: u32, }
let mut buf = MaybeUninit::uninit();
let x: &mut MyCoolStruct = place!( buf, MyCoolStruct { b: true, u: 69420, } );
// SAFETY: buf has been initialized above unsafe { buf.assumeinitdrop() }; ```
