Latest stable rust as a minimum

Minimum supported rust version (MSRV) policy that indicates the most recent stable rust release is the minimum whenever a new crate version is published. It is not required to bump a crate's major version after a new stable compiler is released.

For example crate_foo version 0.1.2 published on 2018-12-28 has MSRV 1.31.1 as this compiler was published on 2018-12-20.

The advantages of this approach is simplicity in maintaining a crate's code.

Workarounds for older compiler versions

If you are unable to update your compiler, you may be unable to update crate dependencies following this policy.

Summary

Panics which happen inside a Drop impl currently unwind as long as the drop was not itself called during unwinding (which would otherwise abort immediated due to a double-panic). This design meeting proposes to change this behavior to always abort if a panic attempts to escape a drop, even if this drop was invoked as part of normal function execution (as opposed to unwinding).

The dicussion on this issue dates back to 2014 (rust-lang/rust#14875) where the decision was made to support unwinding in drops but leave the door open to potentially reversing this decision.

Question

how can I convert an array to a vec without cloning the values

Technically-correct answer

Make a Vec of references:

array.iter_mut().collect::<Vec<_>>();
