Technical notes › Clear out old Rust artefacts with cargo-sweep
A couple of my projects require the Rust “nightly” compiler, and while features are regularly being stabilised, there are still a couple that I need that have not yet made the jump.
As its name suggests, the nightly compiler is updated a lot more often than the stable and beta versions, so nightly build results can and will go out-of-date very quickly. I have a lot of Rust projects, and I don’t want outdated build artefacts to hang around any longer than they need.
The cargo-sweep subcommand is perfect for dealing with this.
To invoke it, I have a script, sweep-rust, that I run after running rustup update.
I pass it the -i flag to remove build artefacts not made by any of the currently-installed compilers, and the -r flag to recurse into sub-directories.
sweep-rust.sh#!/bin/bash -e exec parallel cargo sweep -i -r ::: \ ~/Projects/dog/dog-code \ ~/Projects/exa/exa-code \ ~/Projects/specsheet/specsheet-code
