rustup 1.26.0-7 (s390x binary) in ubuntu oracular

 Rustup installs The Rust Programming Language from the official release
 channels, enabling you to easily switch between stable, beta, and nightly
 compilers and keep them updated. It makes cross-compiling simpler with binary
 builds of the standard library for common platforms.
 And it runs on all platforms Rust supports, including Windows.
