The checking isn't how you shoot yourself in the foot, it's the absence of checking. Rust doesn't allow you to forget to check. This entire class of problems just disappears in Rust.
In this if the code needs a non-null redis client to work you take `RedisClient` not `Option<RedisClient>`.
yes that is correct. tbh in Go for service structs that what you would do as well. use value receivers for such things. and inject dependencies as interfaces. so pointers not immediately visible and it is just type RedisClient interface in your field/arg.
