Expand description

Rustwide is a library to execute your code on the Rust ecosystem, powering projects like Crater and docs.rs.

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!
