predicates features: what each one does, and the line to copy
Short answerpredicates 3.1.4 has 3 features. By default it turns on diff, regex, float-cmp, normalize-line-endings, color; add default-features = false to start from nothing. It needs Rust 1.74 or newer.
Pick features
Every feature
| Feature | In default | Turns on |
|---|---|---|
color | yes | nothing else (a switch the code checks) |
diff | yes | dep:difflib |
unstable | nothing else (a switch the code checks) |
dep:x turns on the optional dependency x; x/y turns on feature y of dependency x (with ?, only if x is already on).
