zinit-annex-rust

A Zsh-Zinit annex that installs rust and cargo packages locally inside the plugin or snippet directories. The crate can then have a so called shim created (name borrowed from rbenv) – a script that's located in the standard $PATH entry "$ZPFX/bin" of following contents (example):

#!/usr/bin/env zsh

function lsd {
  local bindir="/root/.zinit/plugins/zdharma-continuum---null/bin"
  local -x PATH="/root/.zinit/plugins/zdharma-continuum---null"/bin:"$PATH" # -x means export
  local -x RUSTUP_HOME="/root/.zinit/plugins/zdharma-continuum---null"/rustup CARGO_HOME="/root/.zinit/plugins/zdharma-continuum---null"

  "$bindir"/"lsd" "$@"
}

lsd "$@"

As it can be seen shim ultimately provides the binary to the command line.

• Installation
• Usage
  • Options
• Examples
  • Install rust, the lsd crate, and a lsd shim exposing the binary
  • Install rust, the exa crate, and a ls shim exposing the exa binary
  • Install rust and then the exa and lsd crates
  • Installs rust and then the exa' and lsd' crates and exposes their binaries by altering $PATH
  • Installs rust and then the exa crate and creates its shim with standard error redirected to /dev/null
  • Install Rust and make it available globally in the system
  • Use Bin-Gem-Node annex to install the cargo completion provided with rustup

Installation

Load like a regular plugin, i.e.,:

zi light zdharma-continuum/zinit-annex-rust

This installs the annex and makes the rustup and cargo'' ices available.

Usage

The Zinit annex provides two new ices: rustup and cargo''. The first one installs rust inside the plugin's folder using the official rustup installer. The second one has the following syntax:

cargo"[name-of-the-binary-or-path <-] [[!][c|N|E|O]:]{crate-name} [-> {shim-script-name}]'

Options

Flag	description
N	redirect both standard output and error to /dev/null
E	redirect standard error to /dev/null
O	redirect standard output to /dev/null
c	change the current directory to the plugin's or snippet's directory before executing the command

As the examples showed, the name of the binary to run and the shim name are by default equal to the name of the crate. Specifying {binary-name} <- … and/or … -> {shim-name} allows to override them.

Examples

Install rust, the lsd crate, and a lsd shim exposing the binary

zinit ice rustup cargo'!lsd'
zinit load zdharma-continuum/null

Install rust, the exa crate, and a ls shim exposing the exa binary

zi ice rustup cargo'!exa -> ls'
zi load zdharma-continuum/null

Install rust and then the exa and lsd crates

zinit ice rustup cargo'exa;lsd'
zinit load zdharma-continuum/null

Installs rust and then the exa' and lsd' crates and exposes their binaries by altering $PATH

zinit ice rustup cargo'exa;lsd' as"command" pick"bin/(exa|lsd)"
zinit load zdharma-continuum/null

Installs rust and then the exa crate and creates its shim with standard error redirected to /dev/null

zinit ice rustup cargo'!E:exa'
zinit load zdharma-continuum/null

Install Rust and make it available globally in the system

zi ice \
    id-as"rust" \
    wait"0" \
    lucid \
    rustup \
    as"command" \
    pick"bin/rustc" \
    atload='export CARGO_HOME=$PWD RUSTUP_HOME=$PWD/rustup'
zi load zdharma-continuum/null

Use Bin-Gem-Node annex to install the cargo completion provided with rustup

zi for \
    atload='
      [[ ! -f ${ZINIT[COMPLETIONS_DIR]}/_cargo ]] && zi creinstall rust
      export CARGO_HOME=\$PWD RUSTUP_HOME=$PWD/rustup' \
    as=null \
    id-as=rust \
    lucid \
    rustup \
    sbin="bin/*" \
    wait=1 \
  zdharma-continuum/null

When using a global installation of rust in turbo mode, cargos need to omit the rustup ice, and wait on $CARGO_HOME and $RUSTUP_HOME environment variables to be available

zi for \
    wait='[[ -v CARGO_HOME && -v RUSTUP_HOME ]]' \
    id-as'rust-exa' \
    cargo'!exa' \
  zdharma-continuum/null
