Macro impl_init

macro_rules! impl_init {
    ($t:ty; ($($arg:ident: &mut $arg_type:ty),*) $init:block) => { ... };
}

Provides an impl of the Init trait for a type.

This is structured roughly as a function definition. The only acceptable args for it are mutable references to other structures with an Init or Default implementation.

Example

#[derive(Default, PartialEq, Eq, Debug)]
struct InitDependency;

#[derive(PartialEq, Eq, Debug)]
struct InitMe;

impl_init!(InitMe; (_dep: &mut InitDependency) {
    InitMe
});
