Since cargo config get is not stable as of Rust 1.61, nextest must do its own config file search.


  • A store for Cargo config files discovered from disk.
  • An environment variable set in config.toml. See https://doc.rust-lang.org/cargo/reference/config.html#env
  • Environment variables to set when running tests.
  • Represents a target triple that’s being cross-compiled against.



  • Returns the directory against which relative paths are computed for the given config path.
