Trait Storage 

pub trait Storage: Sized {
    // Required methods
    fn from_config(config: &Value) -> Result<Self, PluginError>;
    fn list_items(&self) -> Result<Vec<ItemStat>, PluginError>;
    fn get_item(&self, name: &str) -> Result<String, PluginError>;
    fn put_item(&self, name: &str, content: &str) -> Result<(), PluginError>;
    fn delete_item(&self, name: &str) -> Result<(), PluginError>;
    fn get_resource(&self, resource_id: &str) -> Result<Vec<u8>, PluginError>;
    fn put_resource(
        &self,
        resource_id: &str,
        data: &[u8],
    ) -> Result<(), PluginError>;
    fn delete_resource(&self, resource_id: &str) -> Result<(), PluginError>;
    fn init_new(&self) -> Result<(), PluginError>;
}

存储后端 trait，8 方法镜像宿主 StorageBackend（语义约定见 spec §6.5）： delete_* 幂等（不存在视为成功）；init_new 建根 + .resource/ + 默认 info.json。

Required Methods

fn from_config(config: &Value) -> Result<Self, PluginError>

从数据源配置（与 manifest config_schema 对齐的对象）构造。

fn list_items(&self) -> Result<Vec<ItemStat>, PluginError>

fn get_item(&self, name: &str) -> Result<String, PluginError>

fn put_item(&self, name: &str, content: &str) -> Result<(), PluginError>

fn delete_item(&self, name: &str) -> Result<(), PluginError>

fn get_resource(&self, resource_id: &str) -> Result<Vec<u8>, PluginError>

fn put_resource( &self, resource_id: &str, data: &[u8], ) -> Result<(), PluginError>

fn delete_resource(&self, resource_id: &str) -> Result<(), PluginError>

fn init_new(&self) -> Result<(), PluginError>

Dyn Compatibility

This trait is not dyn compatible.

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