        authority_uri: String,
        table: String,

Expand description

数据源刷新方式。

Variants§

§

Authority

KnowDB V2 权威库单表重载。authority_uri = sqlite 权威库文件 URI; 每次重载重读 CSV → 重灌该表 → 返回全表行(列类型由表目录 DDL 决定)。

Fields

§root: PathBuf

KnowDB conf 所在目录(conf 内 base_dir 相对它解析)。

§conf: PathBuf

KnowDB V2 conf 路径(相对 root 或绝对路径均可)。

§authority_uri: String

sqlite 权威库文件 URI(如 file:/tmp/x.sqlite)。

§table: String

要刷新装载的表名(须在 conf 启用且带 columns.by_header)。

§

NamedSql

命名 SQL provider 直查(facade::query_async_for / facade::query_for)。

Fields

§provider: String

已注册的 provider 名(init_*_provider_named)。

§sql: String

每次刷新执行的 SQL(模板:可含 $name 占位符,由 VEL(见 crate::vel) 每次执行前求值替换)。

§code: String

VEL 变量代码(每行 $name = 字面量/内建函数;空 = 静态 SQL 直接执行)。
