Rust WAS really nice before it got mangled with syntax like we never seen before. Graydon did not imagine rust as what it is today. Rust core wo. async is ok, but in practice rust projects tend to have hundreds of deps and really slow compiles. Its just like javascript with npm.
This is a concern when viewing the Rust experience. It can be avoided by judiciously choosing dependencies that you need, and that have shallow trees of their own. I like to distinguish the rust lang from The rust OSS community. They overlap, but can be treated separately if you exercise case.
