Fixes #7001. Mostly mechanical replacement of `derivative` attributes with `educe` ones. ### **Attribute Syntax Changes** ```rust // Bounds: = "..." → (...) #[derivative(Hash(bound = "E: EthSpec"))] #[educe(Hash(bound(E: EthSpec)))] // Ignore: = "ignore" → (ignore) #[derivative(PartialEq = "ignore")] #[educe(PartialEq(ignore))] // Default values: value = "..." → expression = ... #[derivative(Default(value = "ForkName::Base"))] #[educe(Default(expression = ForkName::Base))] // Methods: format_with/compare_with = "..." → method(...) #[derivative(Debug(format_with = "fmt_peer_set_as_len"))] #[educe(Debug(method(fmt_peer_set_as_len)))] // Empty bounds: removed entirely, educe can infer appropriate bounds #[derivative(Default(bound = ""))] #[educe(Default)] // Transparent debug: manual implementation (educe doesn't support it) #[derivative(Debug = "transparent")] // Replaced with manual Debug impl that delegates to inner field ``` **Note**: Some bounds use strings (`bound("E: EthSpec")`) for superstruct compatibility (`expected ','` errors).

Consensus Specification Tests
This crate parses and executes the test vectors at ethereum/consensus-spec-tests.
Functionality is achieved only via the $ cargo test --features ef_tests command.
Running the Tests
Because the test vectors are very large, we do not download or run them by default. To download them, run (in this directory):
$ make
Note: this may download hundreds of MB of compressed archives from the ethereum/consensus-spec-tests, which may expand into several GB of files.
If successful, you should now have the extracted tests in ./consensus-spec-tests.
Run them with:
$ cargo test --features ef_tests
The tests won't run without the ef_tests feature enabled (this is to ensure that a top-level
cargo test --all won't fail on missing files).
The following is sometimes necessary to avoid stack overflow issues when running on MacOS:
$ export RUST_MIN_STACK=8388608
When debugging failing tests, it's often useful to disable parallization and output suppression:
$ cargo test --features ef_tests,disable_rayon -- --nocapture
Saving Space
When you download the tests, the downloaded archives will be kept in addition to the extracted files. You have several options for saving space:
- Delete the archives (
make clean-archives), and keep the extracted files. Suitable for everyday use, just don't re-runmakeor it will redownload the archives. - Delete the extracted files (
make clean-test-files), and keep the archives. Suitable for CI, or temporarily saving space. If you re-runmakeit will extract the archives rather than redownloading them. - Delete everything (
make clean). Good for updating to a new version, or if you no longer wish to run the EF tests.
