## Announcing cargo-udeps

One of the biggest issues that most people have with Rust are the long compile times. One of the reasons why compile times are so long is because many projects use quite a few dependencies from crates.io.
Your dependencies have dependencies of their own, and they in turn have dependencies as well, and so on. This results in really big graphs of crates that all have to be compiled by cargo.
Sometimes however, a crate actually doesn't use anything of some of its dependencies. Then those dependencies can be removed, resulting in faster builds for that crate.
But how do you detect them? Often they sit in Cargo.toml for a long time until someone discovers they are actually unused and removes them ([example](https://github.com/est31/cargo-local-serve/commit/1e1edf7062807689d0ef22a00784f0a4a8195b9a)). This is where `cargo-udeps` comes in.
[cargo-udeps](https://github.com/est31/cargo-udeps) is an automated tool to find dependencies that were specified in Cargo.toml but never used in the crate itself.

The name is a short form of "unused dependencies" but it is also a name play on the common ascii-ification of the greek µ letter, standing for "micro-deps".
Helping to mitigate the dependency bloat on crates.io is one of the goals of `cargo-udeps`.
