Rust Examples

Disclaimer: there may be errors in these examples. Copy them at your own risk.

Some snippets and examples I want to be able to refer to while learning the Rust Language. Having the snippets here makes it easier for me to remember them.

Convert Vec<T> to Vec<String>

I have found it useful to be able to convert a Vec<T> into a Vec<String>, especially for tests where I want to convert a Vec<str> into a Vec<String> for use elsewhere in the application.

# GNU Screen - main configuration file 
# All other .screenrc files will source this file to inherit settings.
# Author: Christian Wills - cwills.sys@gmail.com

# Allow bold colors - necessary for some reason
attrcolor b ".I"

# Tell screen how to set colors. AB = background, AF=foreground
termcapinfo xterm 'Co#256:AB=\E[48;5;%dm:AF=\E[38;5;%dm'

To get a bash promp that looks like this:

Use this code in your .bashrc file:

source /etc/bash_completion.d/git-prompt
if [ "$color_prompt" = yes ]; then
 #PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

MuslRust-Cross Notes

There are several primary steps:

1. build toolchain with crosstool-ng
2. compile libunwind and add to toolchain
3. compile std with the new toolchain
4. link rust-cross toolchain with rustup
5. build rust binaries :)

Git/GitHub Pro Tips

Checkout github pull requests locally:

• https://gist.github.com/piscisaureus/3342247

Local analytics for git repos:

• https://github.com/ejwa/gitinspector

Replace local branch with remote branch:

ntrepid8

[alias]
	co = checkout
	ci = commit
	st = status
	br = branch
	s = status
	ls = branch --sort=committerdate
	lsa = branch --list --sort=committerdate --all
        lsr = branch --list --sort=committerdate --remotes
	f = fetch
