Feature:代表一个Rust功能,它包含一个功能名称以及支持该功能的编译器版本范围。这个结构体还包含其他元数据,如关于功能的描述和功能是否被弃用等。 State:是一个枚举,用于表示功能的状态。它有三种可能的取值:Unstable表示该功能是不稳定的,Stabilizing表示该功能正在稳定中,Stable表示该功能已经稳定可用。 Stability:是...

On 2.0, we will remove this and enable all unstable features on the nightly channel by default. On the stable, every unstable feature will be disabled. 👎 3 topecongiro closed this as completed Jan 14, 2020 Contributor thomaseizinger commented Jan 14, 2020 • edited Just to clarify...
Each configuration option is either stable or unstable. Stable options can always be used, while unstable options are only available on a nightly toolchain and must be opted into. To enable unstable options, set unstable_features = true in rustfmt.toml or pass --unstable-features to rustfmt....

At the time of writing the article (1.70.0-nightly), the half-open range patterns feature was still unstable and required a dedicated feature attribute to enable it. However, we still provided support for it. The latest Rust plugin releases provide code analysis with the capability to high...
