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.

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:

build toolchain with crosstool-ng
compile libunwind and add to toolchain
compile std with the new toolchain
link rust-cross toolchain with rustup
build rust binaries :)
