This is an analysis of how variadic generics could be added to Rust. It's not a proposal so much as a summary of existing work, and a toolbox for creating an eventual proposal.
Variadic generics (aka variadic templates, or variadic tuples), are an often-requested feature that would enable traits, functions and data structures to be generic over a variable number of types.
To give a quick example, a Rust function with variadic generics might look like this:
| #[derive(Default, Debug, Clone)] | |
| struct Sth { pub log: Option<Log> } | |
| #[derive(Default, Debug, Clone)] | |
| struct Log { pub access: Option<String> } | |
| fn main() { | |
| let sth = Sth { ..Default::default() }; | |
| println!("By default, sth.log.access is not existed, because sth.log is {:?}", sth.log); | |
| #!/bin/bash | |
| # | |
| # Script requires `brew` | |
| # - `/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"` | |
| # | |
| # Variables | |
| # - $IPA -> Source IPA | |
| # - $MOBILEPROVISION -> Source embedded.mobileprovision | |
| # find ~/Library/Developer/Xcode | grep embedded.mobileprovision |
| // How to download telegram sticker images | |
| /* | |
| 1. Go to Telegram Web; | |
| 2. Open console (F12); | |
| 3. Paste the code below in the console and press Enter; | |
| 4. Open your stickers menu and make sure you see the sticker pack you want to download (so Telegram will load it). | |
| 5. At the console paste and run "downloadStickers()" any time you want to download a pack. | |

Friend: I tried looking at static linking in Mac OS X and it seems nearly impossible. Take a look at this http://stackoverflow.com/a/3801032
Me: I have no idea what that
-staticflag does, but I'm pretty sure that's not how you link to a library. Let me RTFM a bit.

| ; Incrementally build a boot block for x86 | |
| ; I'm going to keep adding bits to this one step at a time from | |
| ; boot-and hang to hopefully loading a kernel | |
| ; Here we go. | |
| ; We're implementing a FAT12 file system for the boot disk. This file system is well | |
| ; documented so it shouldn't be a hard ask for a first-timer like me. | |
| ; There is a certain order required for the metadata appearing at the top of the | |
