I can't wait to see how people use default field values in #Rust!

It felt like an eternity to land this (specially if we count the years of discussion before the, I believe, 3rd RFC was accepted), but as of next nightly you will be able to write

struct Foo {

bar: Type = Type::const_method(),

}

Foo { .. } // implicit bar: Type::const_method() call

The main difference between https://github.com/rust-lang/rust/pull/129514 and derive(Default) is that the latter doesn't support having mandatory fields.
