errno features: what each one does, and the line to copy
Short answererrno 0.3.14 has 1 feature. By default it turns on std; add default-features = false to start from nothing. It needs Rust 1.56 or newer.
Pick features
Every feature
| Feature | In default | Turns on |

std | yes | libc/std |
dep:x turns on the optional dependency x; x/y turns on feature y of dependency x (with ?, only if x is already on).
