Rust has very little influence from reflection-heavy languages like Java and C#. On their list of influences (https://doc.rust-lang.org/reference/influences.html https://doc.rust-lang.org/reference/influences.html), Java is not even mentioned, and C# is only mentioned for its attributes. There is very little overlap between the design philosophies that influenced Rust and Java/C#. Ruts does not support inheritance either. But I have never missed either feature in a Rust program.
