static UNSTABLE_FEATURES: &Lint
Expand description
The unstable_features
lint detects uses of #![feature]
.
§Example
ⓘ
#![deny(unstable_features)]
#![feature(test)]
{{produces}}
§Explanation
In larger nightly-based projects which
- consist of a multitude of crates where a subset of crates has to compile on
stable either unconditionally or depending on a
cfg
flag to for example allow stable users to depend on them, - don’t use nightly for experimental features but for, e.g., unstable options only,
this lint may come in handy to enforce policies of these kinds.
