Currently the `Debug` implementation for `MaybeUninit` winds up being
pretty verbose. This struct:
#[derive(Debug)]
pub struct Foo {
pub a: u32,
pub b: &'static str,
pub c: MaybeUninit<u32>,
pub d: MaybeUninit<String>,
}
Prints as:
Foo {
a: 0,
b: "hello",
c: core::mem::maybe_uninit::MaybeUninit<u32>,
d: core::mem::maybe_uninit::MaybeUninit<alloc::string::String>,
}
The goal is just to be a standin for content so the path prefix doesn't
add any useful information. Change the implementation to trim
`MaybeUninit`'s leading path, meaning the new result is now:
Foo {
a: 0,
b: "hello",
c: MaybeUninit<u32>,
d: MaybeUninit<alloc::string::String>,
}

There was a problem hiding this comment.
Suggestion: can this just use MaybeUninit to wrap a type_name::<T>()? It's not like we can rename MaybeUninit right?
