Tower Fallthrough Filter

是否曾想过过滤Tower服务，但又不希望在过滤器不匹配时终止请求？现在可以了！

安装

将以下内容添加到你的 Cargo.toml

[dependencies]
tower-fallthrough-filter = "*"

或者使用 cargo 命令添加

cargo add tower-fallthrough-filter

使用示例

use tower_fallthrough_filter::{Filter, FilterLayer};

#[derive(Clone)]
struct MyFilter;

impl<T> Filter<T> for MyFilter {
    fn filter(&self, _: T) -> bool {
        // This can be any logic you want
        // and can depend on some state stored
        // in the filter itself.

        // When this function returns true, my_service
        // will be called, otherwise the request will
        // fall through to the next service.
        some_buisness_logic()
    }
}

let my_service = MyService::new();
let layer = FilterLayer::new(MyFilter, my_service);

// Now you can use the layer as a normal Tower Layer
