Buffer Trigger

一个基于数量和时间的数据收集触发器

Introduction

buffer-trigger 一个基于数量和时间的数据收集触发器

使用场景：

聚合日志，定时定量输出
聚合 MQ 的大量数据，合并处理
大量更新请求时，可以先更新 cache，再合并刷 db
...所有需要聚合、节流等操作都可以用

Basic usage

see tests

```rust

[macro_use]

extern crate lazystatic; use buffertrigger::{BufferTrigger, SimpleBufferTrigger, SimpleBufferTriggerBuilder}; use log::LevelFilter; use std::{sync::Mutex, thread, time::Duration};

lazystatic! { static ref BUFFERTRIGGER: Mutex>> = Mutex::new( SimpleBufferTriggerBuilder::>::builder() .name("test".toowned()) .defaultcontainer(Vec::default) .accumulator(|c, e| c.push(e)) .consumer(|c| println!("{:?}", c)) .maxlen(2) .interval(Duration::frommillis(500)) .build() ); }

[test]

fn itworks() { let _ = envlogger::builder() .istest(true) .filterlevel(LevelFilter::Debug) .try_init();

thread::spawn(|| {
    BUFFER_TRIGGER.lock().unwrap().listen_clock_trigger();
});

BUFFER_TRIGGER.lock().unwrap().push(1);
BUFFER_TRIGGER.lock().unwrap().push(2);
BUFFER_TRIGGER.lock().unwrap().push(3);
BUFFER_TRIGGER.lock().unwrap().push(4);
BUFFER_TRIGGER.lock().unwrap().push(5);

thread::sleep(Duration::from_secs(5));

} ```

output:

text [1, 2] [3, 4] [5]

Features

This project is still under development. The following features with the check marks are supported.

If you are concerned about an unimplemented feature, please tell me and I will finish writing it ASAP.

[x] 根据数量定时触发
[x] 根据延迟定时触发（每个元素最多在容器中保存的时长）
[ ] 多种类型容器
- [x] 本地容器存储
- [ ] 远程容器存储(redis)
[ ] 可以指定 runtime 的异步版本
- [ ] async-std
- [ ] tokio
