Abusive relationships involve coercion, control, fear, and often violate personal autonomy and consent. One party dominates the other in a
harmful way. Using Rust is not harmful.
Placing restrictions on the programs a programmer can write is not abusive. The rules exist to ensure clarity, safety, performance, and design goals. In an abusive relationship, rules are created to control or punish behavior, often changing capriciously and without reason or consultation. By contrast, Rust is designed by a group of people who work together to advance the language according to a set of articulated goals. The rules are clear and do not change capriciously.
Abuse causes emotional trauma, isolation, and long-term harm. Rust may cause feelings of frustration and annoyance, it may make you a less efficient programmer, but using it does not cause psychological or physical harm found in abusive relationships.
