pub trait Captures<'__> { }
Expand description

The main hack allowing to mention extra lifetime parameters in an impl Trait type without expressing an outlives relationship.

As mentioned in the issues / GitHub comments referenced in the crate docs, this is the main tool to solve the hidden lifetime bugs.

Indeed, it is even officially present among the internal helper types that the very Rust compiler uses for itself: ::rustc_data_structures
