简单的文档化的功能门

这个crate提供了feature_gate和feature_gate_ex宏，用于简单的#[cfg(feature = "...")]宏，这些宏在docs.rs上有良好的文档。

稳定Rust

请注意，为了在稳定Rust上正常工作，目前需要在Cargo.toml中添加以下内容（请参阅自定义构建的元数据）

[package.metadata.docs.rs]
all-features = true
rustdoc-args = ["--cfg", "docsrs"]

示例

feature_gate宏允许指定单个功能

use feature_gate::feature_gate;

#[feature_gate("test")]
struct FeatureGated;

#[test]
fn it_works() {
    let _ = FeatureGated {};
}

feature_gate_ex宏允许指定一组复杂的需求

use feature_gate::feature_gate_ex;

#[feature_gate_ex(any(test, feature = "test"))]
struct FeatureGated;

#[test]
fn it_works() {
    let _ = FeatureGated {};
}
