Trait HostCallHandler 

pub trait HostCallHandler: Send + Sync {
    // Required method
    fn handle_host_call<'life0, 'life1, 'async_trait>(
        &'life0 self,
        method: &'life1 str,
        params: Value,
    ) -> Pin<Box<dyn Future<Output = Result<Value, JsonRpcError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;

    // Provided methods
    fn attach_event_sink(&self, _sink: Arc<dyn PluginEventSink>) { ... }
    fn detach_event_sink(&self) { ... }
}

Maps a host/* method name to the corresponding PluginHandle call. The actual PluginHandle type is provided by src-tauri, so this is a trait-based dispatch to avoid coupling plugin-host to src-tauri.

Required Methods

fn handle_host_call<'life0, 'life1, 'async_trait>( &'life0 self, method: &'life1 str, params: Value, ) -> Pin<Box<dyn Future<Output = Result<Value, JsonRpcError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Handle a host/* RPC call. Returns Ok(serde_json::Value) on success.

Provided Methods

fn attach_event_sink(&self, _sink: Arc<dyn PluginEventSink>)

注入宿主 → 插件的事件推送通道（重启时重新注入，覆盖旧通道）。 默认空实现：不推送事件的宿主可忽略。

fn detach_event_sink(&self)

通知宿主推送通道已失效，注销该插件的订阅回调并取消其定时器。 默认空实现。

Trait Implementations

impl Debug for dyn HostCallHandler

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
