Struct take_mut::scoped::Hole[−][src]

#[must_use]
pub struct Hole<'c, 'm, T: 'm, F: FnOnce() -> T> { /* fields omitted */ }

A Hole<'c, 'm, T, F> represents an unfilled &'m mut T which must be filled before the end of the Scope with lifetime 'c and recovery closure F.

An unfilled Hole<'c, 'm, T, F> that is destructed will try to use F` to fill the hole.

If the scope ends without the Hole being filled, the program will std::process::abort().
