Feature flags

Rustwide provides some optional features that can be enabled with Cargo:

  • unstable: allow Rustwide to use unstable Rust and Cargo features. While this feature also works on Rust stable it might cause Rustwide to break, and no stability guarantee is present when using it!
  • unstable-toolchain-ci: allow fetching toolchains from rustc’s CI artifacts storage. Support for them is incomplete (not all methods might work), and there is no stability guarantee when using them!



  • Command execution and sandboxing.
  • rustwide’s logging system and related utilities.
  • Tools to manage and use Rust toolchains.



  • Error happened while preparing a crate for a build.
