The usual thing for languages is to provide a global allocator. That's what C's malloc is doing for example. We're not asked to specify the allocator, it's provided by the language runtime so it's implied everywhere.
In standalone C, or Rust's no_std, there is no allocator provided, but most people aren't writing bare metal software.
