bytes features: what each one does, and the line to copy
Short answerbytes 1.12.1 has 1 feature. By default it turns on std; add default-features = false to start from nothing. It needs Rust 1.57 or newer.
Pick features
Every feature
| Feature | In default | Turns on |
|---|---|---|
std | yes | 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).
