Struct CompositeSignal 

pub struct CompositeSignal { /* private fields */ }

多信号合并器

监听多个信号源，任一触发即返回

示例

use flare_core_runtime::signal::{CompositeSignal, CtrlCSignal, ShutdownSignal};

let signal = CompositeSignal::new()
    .add(Box::new(CtrlCSignal::new()));

// 或者
let signal = CompositeSignal::from_signals(vec![
    Box::new(CtrlCSignal::new()),
]);

Implementations

impl CompositeSignal

pub fn new() -> Self

创建新的多信号合并器

pub fn from_signals(signals: Vec<Box<dyn ShutdownSignal>>) -> Self

从信号列表创建

pub fn add(self, signal: Box<dyn ShutdownSignal>) -> Self

添加信号

pub fn with_name(self, name: impl Into<String>) -> Self

设置名称

Trait Implementations

impl Default for CompositeSignal

fn default() -> Self

Returns the “default value” for a type.

impl ShutdownSignal for CompositeSignal

fn wait(&mut self) -> Pin<Box<dyn Future<Output = ()> + Send + '_>>

等待信号触发

fn name(&self) -> &str

获取信号名称 (用于日志)
