One callable plugin implementation. 一个可调用的插件实现。

Required Methods§

Source

fn adapter(&self) -> PluginAdapter

The execution adapter that backs this instance. 该实例所依托的执行适配器。

Source

fn call(&self, operation: &str, input: &[u8]) -> Result<Vec<u8>, HostError>

Run one operation against the plugin and return its raw response bytes. The adapter enforces its own limits and reports every failure as HostError. 对插件执行一次操作并返回原始响应字节；适配器自行实施限制，并把所有失败报告为 HostError。
