With literal

Implicit struct initializer for Rust based on this Rust post.

In the future, this literal may allow omitting the .. component if in the future Rust supports a way to infer the struct name.

Limitations

• Requires a base object: either .. for Default::default() or ..o for o

Usage

use with_literal::with;
let y = 0.0;
let o: S = with! { x: 0.0, y, .. };
