Trait Implementations

impl PluginInstance for WasmInstance

fn adapter(&self) -> PluginAdapter

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

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。

fn health_check(&self) -> Result<(), HostError>

Confirm the instance answers a health call with exactly ok. 确认实例对 health 调用给出的回答正好是 ok。
