Parent poster is referring to a full build, which are not really representative of a daily workflow. Incremental builds, in particular of a project where the large part of a full build is on external crates (which don't need to be recompiled) are much faster.

I can't test on an old machine, but modifying the project code and performing an incremental (standard) build, takes around 5 seconds on a modern machine.

Yes

Only on Rust :). This is a "hack" that must be done to make Rust viable. In Delphi, a full compile is so fast that it's pointless to make it incremental.

The biggest issue is lack of support for binary crates in cargo, so instead of pkg-config, you need to build the whole world when starting a new project.

So imagine being on the waiting lobby of an airport, reading about a cool Rust project and then trying to check it on your laptop. With luck it is finished compiling before being called for boarding.
