Alien::Rust(3)

NAME
Alien::Rust - Find or build Rust

SYNOPSIS
Command line tool:

 use Alien::Rust;
 use Env qw( @PATH $RUSTUP_HOME );

 unshift @PATH, Alien::Rust->bin_dir;
 $RUSTUP_HOME = Alien::Rust->rustup_home if Alien::Rust->needs_rustup_home;

DESCRIPTION
This distribution provides Rust so that it can be used by other Perl distributions that are on CPAN. It does this by first trying to detect an existing install of Rust on your system. If found it will use that. If it cannot be found, the source code will be downloaded from the internet and it will be installed in a private share location for the use of other modules.

METHODS

  rustup_home
Returns the value for the environment variable "RUSTUP_HOME". This is valid only if "needs_rustup_home" returns true.

Without this value, certain Rust configurations that use "rustup" <https://rust-lang.github.io/rustup/> will not work as their binaries (e.g., "rustc", "cargo", etc.) are shims that point to the toolchain managed by "rustup".

  needs_rustup_home
Returns true if the value returned by "rustup_home" must be set. See "rustup_home" for more information.
