Descriptions

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.

Se ha detectado un problema en la crate arc-swap versiones anteriores a 0.4.8 (y versiones 1.x anteriores a 1.1.0) para Rust. El uso de la función arc_swap::access::Map con el asistente de prueba Constant (o con una implementación suministrada por el usuario del rasgo Access) a veces podría conllevar a que referencias colgantes sean devueltas por el mapa
