rsfetch
This is a WIP rewrite of rsfetch from scratch.
I've been really unhappy with the codebase now for various reasons.
It's made development for rsfetch downright unpleasant at times.
A blazing fast (<20 ms) information fetching utility.
According to hyperfine anyways.

Extra info
Crate deps and binary size depending on features for rsfetch:
- No Features: 16 crates, 2.5 MB (not stripped), 868 KB (stripped)
music: 20 crates, 2.6 MB (not stripped), 940 KB (stripped)pretty_output: 36 crates, 2.6 MB (not stripped), 1.0 MB (stripped)music,pretty_output: 40 crates, 2.7 MB (not stripped), 1.1 MB (stripped)
Crates explicitely used, and why:

Features
Currently there are 2 features. They are completely optional.
music, this will cause nixinfo to pull in thempdcrate, and display the music info as:
artist - album (date) - title
pretty_output, this will cause rsfetch to pull in theprettytable-rscrate, see example above for how it looks.
Help
$ cargo run -- --help
rsfetch 0.1.0
Phate6660 <https://pages.codeberg.org/Phate6660>
An info fetch tool written in Rust. Everything is off by default, enable what you want.
USAGE:
rsfetch [FLAGS] [OPTIONS]
FLAGS:
-c Display the model of the CPU.
-D Display the name of the device.
-d Display the name of the distro.
-E Display the name of the user's editor. Must have the $EDITOR environmental variable set.
-e Display the user's environment. First checks for a DE, before resorting to parsing your
$HOME/.xinitrc for your WM.
--help Prints help information
-h Display the hostname of the device.
-k Display the name of the kernel.
-m Display free/total memory.
-M Display currently playing music. Only mpd is supported. Must be built with the music feature.
-s Display the name of the user's shell.
-t Display the name of the user's terminal.
-u Display the uptime.
-U Display the name of the user.
-V, --version Prints version information
OPTIONS:
-C, --corner <char> Set the corner character.
-p, --packages <manager> Display package count.
-T, --temperature <C/F> Display CPU temp for Raspberry Pi, must have CPU field enabled.
TODO
- better pretty output by either handling it myself (scary!) or replacing
prettytable-rswith a lighter crate - implement async
- information gathering functions are split off into a separate lib (implemented --
nixinfo)
