bstr features: what each one does, and the line to copy
Short answerbstr 1.13.1 has 4 features. By default it turns on std, unicode; add default-features = false to start from nothing. It needs Rust 1.65 or newer.
Pick features
Every feature
| Feature | In default | Turns on |
|---|---|---|
alloc | memchr/alloc, serde_core?/alloc | |
serde | dep:serde_core | |
std | yes | alloc, memchr/std, serde_core?/std |
unicode | yes | dep:regex-automata |
dep:x turns on the optional dependency x; x/y turns on feature y of dependency x (with ?, only if x is already on).
