I wouldn't rely on that. Next step, someone binds to a blocking database driver and you are back at square 1 again. This is definitely not rigorous. I would love to see a lint for known-blocking constructs in async contexts, though: https://github.com/rust-lang/rust-clippy/issues/4377 https://github.com/rust-lang/rust-clippy/issues/4377 Also, having explicit imports and types that name collide helps there for once.

How would you have a blocking database library that doesn't use the standard library?

  Any code in Rust is free to bind to FFI and sockets can be gained through `libc`.

    I didn't literally mean "How is that possible?" I meant: is that a real thing? Is there a database binding out on crates.io that uses no_std ?

      SQLite is C code and any Rust usage of it will not play nicely with M:N. This is just off the top of my head. I'm sure there are plenty of other examples.

      Yes. E.g. some databases highly recommend using their C library, as they don't consider their protocol specified. That gap might close, but it will stay with us for years.
