There are already a lot of replies to this comment explaining the ideas behind Rust memory management in different ways, but I'll throw in my handwavy explanation as well:

In GC languages, memory management is generally runtime through the interpreter/runtime. In C, memory management is generally done at programming time by the (human) programmer. In Rust, memory management is generally done at compile time by the compiler. There are exceptions in all three cases, but the "default" paradigm of a language informs a lot about how it's designed and used.
