GitHub action for installing rustup

This action provides a simple way to install rustup, the official Rust language toolchain management tool. This action sets the default toolchain to the one specified (or the default, if none is specified).

You can use this action in your workflow directly, or use the all-in-one action for all your Rust CI needs.

Inputs

Input	Description	Default?	Example
`toolchain`	The Rust toolchain to install (i.e., stable, nightly, beta, etc). Refer to https://rust-lang.github.io/rustup/concepts/toolchains.html on how to specify the toolchain.	`stable`	`nightly`
`components`	List of individual components to install after installing rustup. Can be a whitespace or comma separated list.	n/a	`clippy, rustfmt`
`profile`	Override the default rustup profile (for example, 'minimal').	n/a	`minimal`
`allow-downgrade`	Allow rustup to downgrade the installation until all components are available.	`true`	`false`
`targets`	Install additional targets for cross compilation (i.e., 'x86_64-apple-ios, armv7-unknown-linux-musleabi'). Can be a whitespace or comma separate list of targets. Run `rustup target list` to list all targets.	n/a	`aarch64-fuchsia`
`self-update`	Make sure rustup itself is up-to-date before using it. This may fail on some platforms, so it's disabled by default.	`false`	`true`

Outputs

Output	Description
`toolchain`	The Rust toolchain that which was installed.
`rustc-version`	The installed rustc version for the current toolchain.
