[INFO] [stderr] crater-edition-check: migrating to next edition
[INFO] [stderr]    Migrating Cargo.toml from 2018 edition to 2021
[INFO] [stderr] note: Switching to Edition 2021 will enable the use of the version 2 feature resolver in Cargo.
[INFO] [stderr] This may cause some dependencies to be built with fewer features enabled than previously.
[INFO] [stderr] More information about the resolver changes may be found at https://doc.rust-lang.org/nightly/edition-guide/rust-2021/default-cargo-resolver.html
[INFO] [stderr] When building the following dependencies, the given features will no longer be used:
[INFO] [stderr] 
[INFO] [stderr]   either v1.16.0 removed features: std, use_std
[INFO] [stderr]   memchr v2.8.2 removed features: alloc, std
[INFO] [stderr] 
[INFO] [stderr] The following differences only apply when building with dev-dependencies:
[INFO] [stderr] 
[INFO] [stderr]   regex v1.12.4 removed features: default, perf, perf-backtrack, perf-cache, perf-dfa, perf-inline, perf-literal, perf-onepass, unicode, unicode-age, unicode-bool, unicode-case, unicode-gencat, unicode-perl, unicode-script, unicode-segment
[INFO] [stderr]   regex-automata v0.4.14 removed features: dfa-onepass, hybrid, nfa-backtrack, perf-inline, perf-literal, perf-literal-multisubstring, perf-literal-substring, unicode, unicode-age, unicode-bool, unicode-case, unicode-gencat, unicode-perl, unicode-script, unicode-segment, unicode-word-boundary
[INFO] [stderr]   regex-syntax v0.8.11 removed features: default, unicode, unicode-age, unicode-bool, unicode-case, unicode-gencat, unicode-perl, unicode-script, unicode-segment
[INFO] [stderr]   syn v2.0.118 (as host dependency) removed features: default, extra-traits, full, visit, visit-mut
