Struct PluginChain 

Source
pub struct PluginChain { /* private fields */ }
Expand description

插件链(按注册顺序执行)

Implementations§

Source§

impl PluginChain

Source

pub fn new() -> PluginChain

创建空链

Source

pub fn register(&self, plugin: Box<dyn Plugin>)

注册插件(追加到链尾)

Source

pub fn insert_at(&self, index: usize, plugin: Box<dyn Plugin>)

注册插件到指定位置

Source

pub fn unregister(&self, name: &str) -> bool

注销指定名称的插件

Source

pub fn len(&self) -> usize

已注册的插件数量

Source

pub fn is_empty(&self) -> bool

是否为空

Source

pub fn plugin_names(&self) -> Vec<String>

列出所有插件名

Source

pub fn clear(&self)

清空插件链

Source

pub fn execute(&self, context: &mut PluginContext) -> PluginDecision

执行插件链

按 before 插件 → 原操作 → after 插件 的顺序执行。 任意插件返回 Abort 中止整个链。 任意插件返回 Modified 会修改 context 后继续。 任意插件返回 Skip 跳过后续插件(但继续原操作)。
