Summary

Dangling reference in `access::Map` with Constant

Details

Using the arc_swap::access::Map with the Constant test helper (or with user-provided implementation of the Access trait) could sometimes lead to the map returning dangling references.

Replaced by implementation without unsafe, at the cost of added Clone bound on the closure and small penalty on performance.

Summary

Dangling reference in `access::Map` with Constant

Details

An issue has been discovered in the arc-swap crate before 0.4.8 (and 1.x before 1.1.0) for Rust. Use of arc_swap::access::Map with the Constant test helper (or with a user-supplied implementation of the Access trait) could sometimes lead to dangling references being returned by the map.

Severity ?
